Answer : B

Herbivory is an exploitative (+/-) interaction in which an organism—an herbivore—eats parts of a plant or alga, thereby harming it but usually not killing it.

Thorns: Most common morphological means of defense of plants. E.g. Acacia, Cactus etc.

Many plants produce chemicals that make the herbivore sick, inhibit feeding or digestion, disrupt its reproduction or kill it. E.g. Calotropis produce poisonous cardiac glycosides. So cattle or goats do not eat it.

Nicotine , caffeine, quinine, strychnine, opium, etc. are defenses against grazers and browsers.
