Solution

The correct option is B
It germinates to form the pollen tube

Transfer of pollen grains from the anther of stamens to stigma is called pollination. The pollen then elongates to form the pollen tube. The pollen tube grows through the style and reaches the ovule in the ovary and fertilisation takes place.
