Question

besides protecting an endangered or threatened species itself, what else needs to be protected if that species is going to survive?
its name
all of its relatives

The habitat provides the necessary resources like food, water, shelter and the right environmental conditions for breeding and living. Protecting the name or all relatives is not as directly related to the survival of the species as its habitat.

Answer:

C. its habitat
