Static quiz module with predefined answers

I was building a QUIZ module for one website. It is a simple TRUE/FALSE statements where you first choose the answer then correct answer is getting displayed and then you can move forward to next question.

For better understanding, please find working code snippet here: http://jsfiddle.net/ylokesh/Qaf8w/50/

I need mentor guidance in order to make my existing code shorter & optimized. Please guide me.

Here is the jQuery code for this QUIZ module.

var flag = $('.quiz ul'),
    currentPosition = 0,
    currentQuestion = 0,
    slideWidth = 200,
    option = $('.flag'),
    tryCTA = $('.CTAtry'),
    nextQuestion = $('.next'),
    answer = $('span.answer')
    questionWrapper = $('.quiz ul'),
    totalQuestions = $('.quiz ul li').length,
    answers = ["True","False","False"];

//Set UL width    
questionWrapper.css('width',totalQuestions*slideWidth)

  option.on('click',function(e) {
      e.preventDefault();
      var nextCTA = $(this).parent().next(nextQuestion).length,
          optionWrapper = $(this).parent();
      if(nextCTA) {
          optionWrapper.next(nextQuestion).show();
      } else {
          tryCTA.show();
      }
      optionWrapper.parent().find(answer).html(answers[currentQuestion]).show();
      optionWrapper.hide();
  });

  nextQuestion.on('click',function(e){
      e.preventDefault();
      currentPosition = currentPosition+1;
      $(this).parent().parent().animate({
          'marginLeft' : slideWidth*(-currentPosition)
      });
      currentQuestion++;
  });

  tryCTA.on('click',function(e) {
      e.preventDefault();
      resetQuiz(e);
      $(this).hide();
  })

  function resetQuiz(e) {
      $('.quiz ul').animate({
           opacity: 0
      },0)
      .animate({
           opacity: 1            
       },500)

      $('span.answer').html(" ");
      $('.quiz ul').css('margin-left','0');
      $('.options').show();    
      $('.next').hide();
      currentPosition = 0;
      currentQuestion = 0;
  }

HTML:

<div class="quiz">

    <li>
        <span class="answer"></span>

            <span>or</span>
            <a href="" class="flag">False</a>
        </div>
    </li>
</ul>
<a href="" class="CTAtry">Try Again!</a>
</div>

UPDATED CODE : as per Pgraham suggestions. Please suggest other optimization steps which you think can be incorporated in this code to make it crisp.

(function ($, undefined) {
    var currentPosition = 0,
        currentQuestion = 0,
        slideWidth = 200
        optionsWrapper = $('.options'),
        tryCTA = $('.CTAtry'),
        nextQuestion = $('.next'),
        answer = $('span.answer')
        questionWrapper = $('.quiz ul'),
        totalQuestions = $('.quiz ul li').length,
        answers = ["False","False","False","True"];

    questionWrapper.width(totalQuestions*slideWidth)


    $('.flag').on('click',function(e) {
        e.preventDefault();
        var nextCTA = $(this).parent().next(nextQuestion).length,

            selectedAnswer = $(this).html(),
            actualAnswer = answers[currentQuestion],
            displayOptionText = "";

        if(nextCTA) {
            optionWrapper.next(nextQuestion).show();
        } else {

        }

        displayOptionText = (selectedAnswer == actualAnswer) ? "Correct" : "Incorrect";
        optionWrapper.hide().parent().find(answer).html(displayOptionText).show();
    });

    nextQuestion.on('click',function(e){

        });
        currentQuestion++;
    });

    tryCTA.on('click',function(e) {
        e.preventDefault();
        resetQuiz(e);

    function resetQuiz(e) {
        questionWrapper.animate({ opacity: 0 },0)
                       .animate({ opacity: 1 },500)
