Conifer resin ducts, which are found in the cortex and phloem, contain a mixture of diverse terpenoids, which are released immediately upon damage by herbivores such as;
a) monocyclic terpenes like- limonene and terpinolene
b) bicyclic monoterpenes- α-pinene and β-pinene
c) tricyclic sesquiterpenes- longifolene, caryophyllene, and δ-cadinene
d) tetracyclic terpenes- longifolene, tetra-terpinolene terpenoids are incorrect?

Members of the Poaceae family, which includes all of the cereal crops, use benzoxazinoids, these alkaloids shows;
a) Alkaloids are derived from the tryptophan as constitutively produced defensive secondary metabolites
b) These benzoxazinoids such as DIBOA and its derivative DIMBOA are usually stored in the peroxisome
c) Upon damage, the inactive glycosides are hydrolyzed, generating glucosinolate, which are toxic not only to insect herbivores but also against pathogens
d) DIBOA and DIMBOA perform insecticidal and pesticidal activities
e) It can be inactivated by hydroxylation and N-glycosylation reactions
Which of the following combination is correct about benzoxazinoids alkaloids?
