Answer:
The correct answer of this question is- C) production of chemical compounds for defense or to attract predators
Explanation:
In response to attacks by herbivores, plants produce chemicals that are toxic to the herbivores which can even kill them or some chemicals can spread in the air and can attract the predators of those herbivores that attack that plant species.
Plants produce secondary metabolites that play an important role in protecting the plant from predators because they can be toxic and antimicrobial for example flavonoids, alkaloids, saponins. Plants do not get harmed by these metabolites because they have their own detoxification method. So the correct answer is C.
