Answer:
Correct Answer: C
Solution:
Cochineal is an insect that feeds on certain species of cactus and from which a scarlet dye is obtained. These included two species of the cochineal insect (Dactylopius ceylonicus and D. confuses) and the cactoblastis moth (cactoblastis sp). It lives primarily on the prickly pear cactus by feeding on moisture in its leaves. Thus, it acts as a stress on the plant.
