B. Selection bias.
C. Instant history bias.
Explanation: This leads to an incorrect or inflated presentation of the performance of the fund during their incubation period, leading to the "backfill bias" or the "instant history bias".

FARHANR Why isn't the answer B?
sikwingo Lol, also thought same answer
leon121 selection bias refers to the tendency to exclude a certain part of a population simply because the data is not available. (in this case, data WAS available)....As a result, we cannot state that the sample we've drawn is completely random - it is random only within the subset on which historic data could be obtained
