Step 1: Zoonoses are classified two different ways. By the type of life cycle they are divided into direct zoonoses, cyclo-zoonoses, meta-zoonoses, and sporo-zoonoses.
Step 2: By the direction of transmission they are divided into anthropozoonoses, zooanthroponoses, and amphixenoses. Anthropozoonoses therefore belongs to the transmission-direction grouping, not the life-cycle grouping.
Step 3: Since the question asks which one is not a life-cycle category, the answer is anthropozoonoses, option c. The other three options are all genuine life-cycle categories.
