Answer 2

Answer:

Option 3 is the right answer

Explanation:

=> LDP stands for Long Day Plants.

=> When the plant flower is exposed to photoperiod longer than the length of critical day are considered as Long Day Plant or simply LDPs.

=> In the case of Long Day Plants a brief exposure of light in the dark period stimulates flowering.

=> There is critical light period for LDPs.

=> Flowering can be induced by gibberellin in the case of LDPs even if in the non-inductive photo period condition.

=> Other Examples - Henbane, Spinach, Barley etc.
