B. Selective hunting favored tuskless individuals who survived to reproduce.

Explanation: Ivory hunting removed tusked elephants from the breeding population, so tuskless females had higher survival and reproductive success — a clear case of human-caused selection. Random drift, new mutations after the war, or migration are far less likely to produce the rapid, targeted increase in tusklessness.
