What sort of novels is this person reading for them to be more expensive per hour than a movie in a theatre?

Maybe he hates reading and only enjoys a book for 10 minutes? For a $1 thriller novel the chart checks out.

There are 3 possible answers '25%' or '33%' or '50%' .
One of them must be correct, else the question is invalid (since then the answer is '0%' and there isn't a choice of that in the possible answers)

Pick ABCD at random. There is a 2/4 chance of being right if the answer is '25%' and a 1/4 chance for both '50%' and '33%'

so [ (2/4)+(1/5)+(1/5)+(2/4) ]/4 = 37.5%

In which case, 37.5% is the right answer, but not a choice. Therefore you have a 0% chance of guessing the right answer
