Answer: (D)

Verified step by step guidance

1. Understand the role of the endocrine system: It is a network of glands that produce and release hormones to regulate various bodily functions, including metabolism, growth, and stress response.
2. Recognize that exercise is a physical stressor that activates the body's systems to maintain homeostasis and meet increased energy demands.
3. Identify key hormones involved during exercise, such as adrenaline (epinephrine) and cortisol, which are released by endocrine glands like the adrenal glands.
4. Explain how these hormones help the body respond to exercise by increasing heart rate, mobilizing energy stores, and managing stress.
5. Conclude that exercise stimulates the endocrine system by increasing hormone production and release, rather than decreasing it or having no effect.
