Explanation:

Parasites rely on their host for resources like food and shelter. If they kill the host, they lose this resource and have to find a new host, which is difficult. So, they usually don't try to kill the host. Option A is incorrect as parasites don't have emotions like sadness. Option B is wrong as it's not the typical case. Option D is false as parasites' behavior is about survival, not kindness.

Answer:

C. They would have to find another host.
