The options that stipulate conditions about when excretion of a substance will occur are:
- Secretion is greater than reabsorption.
- Reabsorption is less than filtration and there is no secretion.
<h3>What is excretion?</h3>
Excretion is the removal of waste substances from the body. Often secretion takes place when there is an accumulation of waste in the human body. Reabsorption occurs when solutes and aqueous substances go back into the plasma.
If secretion ceases and filtration continues without reabsorption, we can expect excretion to occur. So, the first two options satisfy the conditions for excretion.

Answer:
A) Stigma
Explanation:
This option makes the most sense of all of them. The food storage option is incorrect because food storage is a part of a seed. The stigma is part of producing the seed, not part of the actual seed. The testa is the seed coat (part of a seed). The plumule is also part of a seed (stem or seedling).
Hope it helps!
