The correct answer is: 4) Standing defenses are always present; induced defenses develop in response to a threat

Induced defense is defense that can be changed or invoked when needed. Induced defenses are slow to happen. When invoked, induced defense requires energy but otherwise doesn’t.

Standing defense is always there. It is use, for example when predation is a constant threat.
