Im pretty sure the correct answer is comma.
<span>Indicating a pause between parts of a sentence or separating items in a list. </span>
It says "should be used between each item" so it isn't any of the other choices.
Hope this helps!

The context clues are re hints that an author gives to help define a difficult or unusual word. Remember that those words <span>may appear within the same sentence as the word to which it refers, or it may follow in a preceding sentence. For the word dissaprobation, you have the following context clues: Terror, Horror, disgust, A buzz and murmur. The rest of the words given are not context clues for disapprobation</span>
