Correct answer is C
The presence of water is the most important factor. Without water, cells cannot carry out their necessary activities and the seed will not germinate. When a seed absorbs water, it is called Imbibition. Water enters the seed either through a tiny opening in the seed called the micropyle or through the seed coat. The micropyle is also the site at which the pollen tube enters the ovule during fertilization.
