Here, a LIST of actions is attributed to the bats:
AIDING in the dispersal of cashew, date, and fig seeds
POLLINATING banana, breadfruit, and mango trees
HELPING to produce tequila.


The primary issue here is PARALLELISM.
Only in B are the three actions parallel (aiding, pollinating, helping).
Eliminate A, C, D and E.

The correct answer is B.
