Explanation:

A functional adaptation is a physiological or behavioral trait that helps an organism survive and reproduce. A male bird's mating call (Option A) is a behavioral trait that aids in reproduction. Poison dart frogs' toxic venom (Option B) is a physiological defense mechanism. Cobras elongating their bodies and hissing (Option C) is a behavioral threat display. A flounder's camouflage (Option D) is a structural adaptation. Among these, the male bird's mating call is a clear example of a functional (behavioral) adaptation for reproduction.

Answer:

A. A male bird lets out a mating call to attract a female bird.
