Answer: (A)

Verified step by step guidance

1. Identify the key function described in the problem: the secretion of hormones that regulate sexual behavior and reproduction.
2. Understand the role of each option provided: gonads, adrenal glands, neurotransmitters, and neurons.
3. Recognize that gonads (ovaries in females and testes in males) are primarily responsible for producing sex hormones such as estrogen, progesterone, and testosterone, which are crucial for sexual behavior and reproduction.
4. Consider the function of adrenal glands, which produce hormones like adrenaline and cortisol, primarily involved in stress response rather than directly regulating sexual behavior.
5. Acknowledge that neurotransmitters and neurons are involved in transmitting signals in the nervous system, not in hormone secretion related to sexual behavior and reproduction.
