When pages and MC options are random, how to find out what was actually chosen?

When pages and multiple choice options within a quiz are random, how do you interpret detailed LMS data? Moodle tells me whether or not the learner got the question right and the letter of the MC option they chose (choice A, B, C, D), but it doesn't tell me the answers that those letters represent. Is there any way to figure out which option they actually chose? I'd like to know which wrong answers students are choosing.
