Answer 2

In gymnosperms, pollen drop is the C) Secretion of the nucellus.

Gymnosperms are plants with exposed seeds or plants without a flower, due to this most of these plants rely on abiotic factors such as the wind to carry out pollination. During this process, the pollen grains carried by the wind reach the female gametophyte or the ovule.  

In order to ensure that the pollen grain attaches itself to the ovule to successfully carry out sexual reproduction, the fleshy portion of the ovule called the nucellus produces a thick sticky and nectar like fluid, which like the stigmatic secretion seen in angiosperms. The pollen grains attach themselves to the ovule due to the pollen drop, leading to pollen tube formation and eventually fertilization.
