The hormones that stimulate ovulation are produced in the pituitary gland. These hormones are known as Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH).

Here's a step-by-step explanation:

1. The pituitary gland, located at the base of the brain, produces several hormones. Among these are LH and FSH, which play crucial roles in the menstrual cycle.

2. FSH is responsible for the growth and maturation of follicles in the ovaries. Each follicle contains an egg.

3. As the follicles mature, they start to produce another hormone called estrogen (oestrogen).

4. The rising levels of estrogen trigger the pituitary gland to release LH.

5. The surge in LH levels causes the most mature follicle in the ovary to burst and release its egg. This process is known as ovulation.

6. After ovulation, the ruptured follicle transforms into a structure called the corpus luteum, which produces progesterone. This hormone prepares the uterus for potential pregnancy.

So, the correct answer to your question is d. LH and c. FSH.
