Either the idea of the question flew completely over my head or at its core this is really simple arithmetic veiled with complicated wording.
A is 50 because there are 100 percentiles and 50 integers between 151 and 200 inclusive => every integer has exactly two percentiles. And by this logic B should be 2?
Correct me if I'm wrong.

The minimum number of integers that include more than 1 percentile group, which means that whats the lowest number of a scores that can have more than 1 percentile group. If all 400 people get the same score, then that's one integer value that has all the percentiles.

The minimum number of percentile groups that correspond to a score of 200, well... what if no one gets a 200? then that's no integer values at all.

thus choice A =1
choice B = 0

A is greater
