Question

male ducks molt:
after breeding season
in spring
in winter
never

Explanation:

Male ducks (drakes) typically undergo molting after the breeding season. This is part of their natural life cycle, where they replace their feathers, often losing their colorful breeding plumage and temporarily being unable to fly during this period. Spring and winter are not the typical times for their main molt, and they do molt, so "Never" is incorrect.

Answer:

A. After breeding season
