Which of the following behaviors is best classified as a taboo in most societies, and why does it fit this classification?

A taboo is a behavior that is strongly discouraged and considered unacceptable in most societies. One example of a taboo is incest, which is sexual relations between close relatives. This behavior is classified as a taboo because it goes against deep-seated cultural norms and values about family relationships and the potential negative consequences for offspring. Societies often enforce taboos through laws or social ostracism to protect individuals and the community. Thus, incest is seen as harmful not just to the individuals involved, but also to the social structure as a whole.
