Final answer:
The correct illustration of a fixed action pattern from the provided options is (C) A baboon rising on hind feet when threatened, as this behavior is an innate, hardwired response that automatically completes once initiated.
Step-by-step explanation:
A fixed action pattern is an innate, preprogrammed response to a specific stimulus that, once initiated, runs to completion regardless of whether the initial stimulus is still present. This type of behavior is not learned; it is hardwired and will occur the same way every time in response to the stimulus. A classic example provided in the question's context is the reaction of male three-spined sticklebacks, which attack a red-bottomed object mistaking it for a rival male stickleback, displaying such a fixed action pattern.
The best example that illustrates a fixed action pattern from the given options is (C) A baboon rising on hind feet when threatened. This is because the baboon's behavior is an instinctual and predictable reaction to a threatening scenario and will be carried out to completion once initiated, similar to the stickleback's response to the red stimulus.
