a) secondary metabolites also fuction in defence mechanism but this is not the volatile compound

b) These volatiles can act as cues for natural enemies of the insect herbivore such as parasitic wasps

c) All plants releases green-leaf volatiles in response to mechanical damage that is a mixture of aldehydes, alcohols, and esters

d) These volatiles attracts natural enemies of the attacking insect herbivores—predators or parasites
