The sentence is “she understands who amongst their trio is tasked with protecting everything.” Should it be “whom” because the person is receiving the task of protecting, or “who” because they do the action of protecting?
Thank you.

It isn't relevant who is "receiving" or "doing" an action. What matters is the syntactic role that the noun phrase "who amongst their trio" plays in the interrogative clause "who amongst their trio is tasked with protecting everything." In this case, we see that "who amongst their trio" is the subject of that clause; it plays the same role that "He" does in "He is tasked with protecting everything." Since it is the subject, only who would make sense; using whom here would be incorrect.
