What will be the effect light in GA biosynthesis?

a) Light basically activates the GA 3β-hydroxylase which adds a hydroxyl group (OH) to carbon 3 of GA20 and convert GA20 to GA1

b) light-induced increase in the transcription of the gene for GA3ox, which converts GA20 to GA1

c) light-induced increase in the transcription of the gene for GA2ox, which converts GA20 to GA29

d) light-induced decreases the transcription of the gene for GA3ox, which converts GA20 to GA1
