Clarify this option in Quiz Editing: "Let Students See Their Quiz Responses (Incorrect Questions Will Be Marked in Student Feedback)" and save.
This is very confusing and I checked the box thinking the students would be able to only see the answer they selected, but it gave the students access to all of the questions and all of the answers thereby blowing my exam security for protecting my questions.

Allow students to only see feedback. etc.
