Answer 1

The correct option is D Florigen

Florigen (or flowering hormone) is the hypothesised hormone-like molecules responsible for controlling and/or triggering flowering in plants. Florigen is produced in the leaves and acts in the shoot apical meristem of buds and growing tips. It is known to be graft-transmissible, and even functions between species.

So, the correct answer is option D.
