A multiple-choice question has 6 choices. But choice 6 is blank.
The question should show 5 choices: A. B. C. D. E.
Instead the question shows 6 choices, A. B. C. D. E. F., with one of the choices blank.
Since the answers are shuffled, I get something like:
A. Jkfjasl akfjas sdjf
B. alksjfas aksfjas lskfjla
C. alskfja alskfj asjf k
E. sadkfasjd laksdfj kjkj kjdslakf
F. asjfkas lkasfj kadkjf
