Environmental factors such as photoperiod and temperature can alter the levels of active gibberellins by affecting gene transcription for specific steps in the biosynthetic pathway such as;

a) Promotion of germination by light has been shown to be due to increases in GA1 levels resulting from a light-induced increase in the transcription of the gene for GA3ox, which converts GA20 to GA1

b) level of GA20-oxidase occurs in the highest amount in shoot tips and elongating stems, is increased under long-day conditions.  The fact that GA 20-oxidase is the enzyme that converts GA53 to GA20

c) Giving cold treatment  of Thlaspiarvense and a return to high temperatures, the ent-kaurenoic acid is converted to GA9, the most active gibberellin for stimulating the flowering response

d) Potato plants overexpressing the GA20ox gene showed tuberization, whereas transformation with the antisense gene for GA20ox inhibited tuberization

Which of the following from the given above statements is correct?
