Yawning is observed in all types of animals, including humans. It cannot be stopped midway but has to be continued to completion. What kind of an innate behavior is yawning?

A. Habituation

B. Fixed action pattern

C. Imprinting

I think the correct answer from the choices listed above is option B. Yawning is a fixed action pattern type of innate behavior. This behavior is an instinctive behavioral sequence and it inevitably runs into completion which means it cannot be stopped. Hope this answers the question.
