Correct option is (b) Opium
 
Easiest explanation: Opium is the chemical produced by plants against grazers and browsers. These are secondary metabolites. Along with this plants also produce alkaloids, benzoxazinoids, cyanogenic glycosides, glucosinolates, terpenoids, and phenolics for chemical defense.
