There are a few criteria one can use for choosing intervals.

make the intervals as uniform as possible cover the range in a "reasonable" number of intervals appropriately reflect the data distribution make the boundaries unambiguous

Selection B has boundaries that overlap, so can be ruled out immediately. Selection D has ranges that go from 19 to 9, so does not have very uniform intervals. Likewise, selection A defines the first interval to be twice the width of the others, so it isn't a good choice, either.

IMO, the best of the offered choices is ...
