Final answer:
The kinship terminology with terms M=MZ=FZ and F=FB=MB is a description of bifurcate merging kinship terminology, common in unilineal descent societies.
Step-by-step explanation:
The kinship terminology that describes the relationships where M=MZ=FZ and F=FB=MB correctly corresponds to a bifurcate merging kinship system. In this system, kinship terms merge EGO's parents' same-sex siblings and their offspring into the immediate family as parallel cousins, while bifurcating the opposite-sex siblings and their offspring as cross cousins. This is indicative of societies with unilineal descent, where kinship and familial responsibilities are focused on either the mother's or father's side, but not both. The bifurcate merging kinship system is distinct from other kinship systems like lineal, bilateral, and generational, each defining family relations and obligations differently. Given the specified kinship terms, the accurate description of the kinship system in question would be bifurcate merging kinship terminology (option a).
