Following are given stages of gibberellin biosynthetic pathway;

a) Geranylgeranyl diphosphate (GGPP) is converted to ent-kaurene  via copalyl diphosphate (CPP) in endoplasmic reticulum

b) In the endoplasmic reticulum, conversion of ent-kaurene into GA12 or GA53 depending on whether the GA is hydroxylated at carbon 13

c) the conversion of GA12 or GA53 into other GAs in cytosol proceeds with a series of oxidations at carbon 20

d) GA20 is then oxidized to the active gibberellin, GA1, by a 3β-hydroxylation reaction

Which of the following is the correct statements of GA biosynthesis?
