D.) disgust
Explanation
Lets look at the whole sentence with the worh replaced:
Even though his dog had chewed it up, Trevor handed his homework to his teacher, who struggled to hide her disgust at the sight of the half-chewed, drool-soaked paper.
Disgust best replaces “revulsion” because of course, what tacher wouldnt be disgusted about a homework chewed up by a dog? And teachers hide it so they wont give a bad impression to the student. It didnt change the overall meaning of the sentence too!
