JavaScript Interacting with options

I currently have a dropdown list... to finish blank sentences off.

The problem I have is Uncaught TypeError: Cannot read property 'options' of null

Here is a snippet of my HTML 

<section class="question-three">
                <h4>Question 3</h4>
                <ol>
                    <li>A partnership is a business entity 
                    <select id="selectionOne">
                        <option value="#">Please Select...</option>
                        <option value="sole trader">sole trader</option>
                        <option value="members">members</option>
                        <option value="shareholders">shareholders</option>
                        <option value="run">run</option>
                        <option value="limited company">limited company</option>
                        <option value="owned">owned</option>
                    </select>
                    by two ore more people who carry a business collectively with a view to making a profit.
                </li>

JavaScript

var dropDownList = {
    answers: ['sole trader', 'members', 'shareholders', 'run', 'limited company', 'owned'],
    checkAnswer: function() {
        var check = document.getElementById('selectionOne');

        if(check.options == dropDownList.answers[5]) {
            console.log('The answer is right!');
        } else {
            console.log('false')
        }
    }
};

dropDownList.checkAnswer();

Could anyone please help me?

Thank You

You are not accessing the value. We also do not know when you trigger the event. You need to assign it after the select has rendered:

var dropDownList = {
    answers: ['sole trader', 'members', 'shareholders', 'run', 'limited company', 'owned'],
    checkAnswer: function() {
        var check = document.getElementById('selectionOne');

        if(check.value == dropDownList.answers[5]) {
            console.log('The answer is right!');
        } else {
            console.log('false')
        }
    }
};
window.onload=function() {
  document.getElementById("checkIt").onclick=function() {
    dropDownList.checkAnswer();
  }
  // or document.getElementById("selectionOne").onchange
}
<section class="question-three">
                <h4>Question 3</h4>
                <ol>
                    <li>A partnership is a business entity 
                    <select id="selectionOne">
                        <option value="#">Please Select...</option>
                        <option value="sole trader">sole trader</option>
                        <option value="members">members</option>
                        <option value="shareholders">shareholders</option>
                        <option value="run">run</option>
                        <option value="limited company">limited company</option>
                        <option value="owned">owned</option>
                    </select>
                    by two ore more people who carry a business collectively with a view to making a profit.
                </li>
<button id="checkIt">Check</button>
