With reference to the human body consider the following statements: 1. The production of somatotropin goes up when a person exercise 2. Men's testes produce progesterone 3. Women's adrenal glands secrete testosterone 4. Stress causes the adrenals to release very less amount of cortisol than usual Which of these statements are correct?

A

1 and 3 only

B

1,3 and 4 only

C

2,3 and 4 only

D

1,2,3 and 4

Correct Answer: Option A

Explanation

1. Statement 1 is correct. Exercise stimulates the pituitary gland to release Growth Hormone (somatotropin). The production (release) of somatotropin goes up during and after physical exercise. 2. Statement 2 is incorrect. Men's testes primarily produce testosterone (an androgen). While they produce trace amounts of progesterone, it is not their main product; progesterone is primarily a female sex hormone produced by the ovaries and placenta. 3. Statement 3 is correct. While testosterone is the primary male sex hormone, women's adrenal glands (and ovaries) also secrete small amounts of androgens, including testosterone, which play roles in female physiology. 4. Statement 4 is incorrect. Stress triggers the 'fight-or-flight' response, causing the adrenals to release significantly *more* cortisol (a primary stress hormone), not less. 5. The question asks for correct statements, but the options (A, B, C, D) seem to be matching codes (like A-2, B-4...), which doesn't fit the question format 'Which of these statements are correct?'. Assuming the options refer to which statements are correct, and given the answer 'd', let's re-examine. If answer 'd' implies Statements '1 and 3' are correct (based on common option formats, though not shown here), this aligns with our analysis above. However, the options provided (A-2, B-4, C-3, D-1 etc.) suggest a matching format was intended but the question text is a statement verification type. Assuming the provided answer 'd' corresponds to a hypothetical option like '(D) 1 and 3 only' which is missing: statements 1 and 3 are correct. *Analysis based on reinterpreting the likely intended format corresponding to answer 'd'.*
