Which of the following statements are correct ?
(a) Cortisol suppresses the immune response
(b)Thyroxine supports the process of red blood cell formation
(c) Glucagon stimulates glycogenesis process
(d) Androgens stimulate muscular growth, aggressiveness, high pitch of voice.

Options

A. a, b, c are ture, but d is false
B. a, b, d are true, but c is false
C. d is true, but a, b, c are false
D. a, b are true, but c, d are false

Answer

To determine which of the statements are correct, let's analyze each one step by step:

### Step 1: Analyze Statement (a)
**Statement (a): Cortisol suppresses the immune response.**
- Cortisol is a steroid hormone produced by the adrenal cortex. It is known to have immunosuppressive effects, meaning it can reduce the activity of the immune system. This statement is **correct**.

### Step 2: Analyze Statement (b)
**Statement (b): Thyroxine supports the process of red blood cell formation.**
- Thyroxine (T4) is produced by the thyroid gland and plays a role in various metabolic processes, including the stimulation of erythropoiesis (the formation of red blood cells). This statement is **correct**.

### Step 3: Analyze Statement (c)
**Statement (c): Glucagon stimulates glycogenesis process.**
- Glucagon is a hormone produced by the pancreas that raises blood glucose levels by promoting glycogenolysis (the breakdown of glycogen to glucose) and gluconeogenesis (the production of glucose from non-carbohydrate sources). It does not stimulate glycogenesis (the formation of glycogen from glucose). This statement is **incorrect**.

### Step 4: Analyze Statement (d)
**Statement (d): Androgens stimulate muscular growth, aggressiveness, high pitch of voice.**
- Androgens are male sex hormones, such as testosterone, that are known to promote muscle growth and can influence behavior, including aggressiveness. However, androgens are associated with a lower pitch of voice rather than a high pitch. Therefore, this statement is **partially correct** but ultimately **incorrect** due to the high pitch of voice claim.

### Conclusion
Based on the analysis:
- Statement (a) is correct.
- Statement (b) is correct.
- Statement (c) is incorrect.
- Statement (d) is incorrect.

Thus, the correct statements are **(a) and (b)**.

### Final Answer
The correct statements are: **(a) and (b)**.
