Correct Option: (D) GA3 initiates enzyme hydrolases synthesis to digest and mobilise the seed’s reserve food materials.

GA3 (gibberellic acid) is a hormone that initiates the synthesis of hydrolysis enzymes in the seeds to digest and mobilize reserved foods, leading to the loss of seed lethargy for embryonic development.
