Hello there, It would be a pleasure to help you!
Answer:
-Option B.
-Option C.
Step-by-step explanation:
Seeds do not contain much water, and this is part of why water is part of the external signals that make a seed germinate.
One of the ways that water is involved is called imbition, where the dry seed absorbs water and swell, and this causes the seed coat to break (C), which will allow the seedling to emerge and grow.
The seed contains the nutrients needed for germination, but for this reserve to be used it needs enzymes that remain inactive until enough water is present (B).
