Answer: D [Abscisic acid]
Explanation:

Abscisic acid (ABA) is a plant hormone that functions as a growth inhibitor. It plays a major role in responses to environmental stress, such as drought, by causing the stomata to close. It also promotes seed dormancy and is associated with the wilting of leaves.

Answer: B [To induce the production of more eggs than in a normal cycle (super ovulation).]
Explanation:

MOET is a programme for herd improvement. The key first step is to administer hormones, such as Follicle-Stimulating Hormone (FSH), to a high-quality female (cow). This induces follicular maturation and super ovulation, causing her to produce 6-8 eggs in a cycle instead of the usual one. These eggs can then be fertilized and transferred to surrogate mothers.
