Question

why do parasites typically avoid killing their host? parasites are kind - hearted. parasites try to benefit their host. it is more challenging to find a new host. parasites usually do kill their host.

Explanation:

• "Parasites are kind - hearted" is incorrect as parasites act out of self - interest for survival, not kindness.
• "Parasites try to benefit their host" is wrong because parasites derive benefits at the host's expense, not to benefit the host.
• "It is more challenging to find a new host" is correct. Parasites rely on the host for resources (like nutrients, shelter). If they kill the host, they lose their source of survival and finding a new host can be difficult, so they avoid killing the host to continue exploiting it.
• "Parasites usually do kill their host" is incorrect. Most parasites have a symbiotic (parasitic) relationship where they keep the host alive to sustain themselves; killing the host is not typical for most parasites.

Answer:

C. It is more challenging to find a new host.
