Answer: (B)

Verified step by step guidance

1. Step 1: Understand the role of hormones in the body. Hormones are chemical messengers that regulate various physiological processes, including growth, metabolism, and stress responses.
2. Step 2: Review the function of each hormone listed in the problem: - Insulin: Regulates blood sugar levels by facilitating glucose uptake into cells. - Adrenaline: Also known as epinephrine, it is involved in the 'fight or flight' response, increasing heart rate and energy availability. - Cortisol: Known as the stress hormone, it helps regulate metabolism and immune responses during stress. - Growth Hormone (GH): Stimulates cell growth, reproduction, and regeneration, playing a key role in healing and development.
3. Step 3: Focus on the specific action described in the problem: promoting cell growth and regeneration. This is a key function of Growth Hormone (GH).
4. Step 4: Eliminate the other options based on their primary functions. Insulin, adrenaline, and cortisol do not primarily stimulate cell reproduction and healing.
5. Step 5: Conclude that Growth Hormone (GH) is the correct answer because it directly promotes cell growth and regeneration, aligning with the description in the problem.
