Answer: Option A
: A
For the completion of their life cycle, some parasites require more than just the host. For example, tapeworm completes its life cycle in humans and cows/pigs. In humans which is the definitive host, it multiplies and causes the symptoms. In cows and pigs (the reservoir host), it just resides and does not show any ill effects.
