The Route Followed by a Sperm from Production to Fertilization

The route followed by a sperm from production to fertilization in a flowering plant is:

A) A sperm cell,enclosed in a pollen grain with another sperm,is produced in the pistil that explosively ejects it into the air where it is transported to a stigma from which it passes through a pollen tube that grows down the style to the ovary,enters the ovule and joins with the egg cell.
B) A sperm cell,enclosed in a pollen grain with another sperm,is produced in the anther,transported to a stigma where it passes through a pollen tube that grows down the style to the ovary,enters the ovule and joins with the egg cell.
C) A sperm cell,enclosed in a pollen grain with another sperm,is produced in the filament,transported to a stigma where it passes through a pollen tube that grows down the style to the ovary,enters the ovule and joins with the egg cell.
D) A sperm cell,enclosed in a pollen grain with another sperm,is produced in the anther,transported to the pedicel where it passes through a pollen tube that grows down the style to the ovary,enters the ovule and joins with the egg cell.
E) A sperm cell is produced in the anther,transported to a stigma where it becomes enclosed along with another sperm cell into a pollen grain that grows down the style to the ovary,enters the ovule and joins with the egg cell.
