• C. Testosterone, cortisol, and thyroid hormone
• D. Prolactin, oxytocin, and somatostatin

Answer: (B)

The ovaries play a crucial role in the female reproductive system by producing key hormones necessary for various physiological processes. The primary substances produced by the ovaries are estrogen, progesterone, and androgens, collectively critical for regulating the menstrual cycle, maintaining pregnancy, and influencing secondary sexual characteristics.

Estrogen is important for the development of female secondary sexual characteristics, regulation of the menstrual cycle, and overall reproductive health. Progesterone prepares the uterine lining for potential implantation of a fertilized egg and maintains that lining during pregnancy. Androgens, although often categorized as male hormones, are also produced in smaller amounts in females and contribute to various metabolic processes and the overall hormonal balance.

This combination of hormones reflects the ovaries' essential functions in reproductive health, differentiating them from the other hormones listed in the other choices, which are produced by different glands, such as the pancreas and adrenal glands, or are unrelated to ovarian function.
