Read the following statements about adrenal hormones. Select the correct one.

Options

A. Aldosterone sitmulates the reabsorption of `Ca^(2+)` and water from the renal tubules.
B. Cortisol is a major glucocorticoid
C. Glucocorticoids promote cellular uptake and utillisation of amino acids.
D. Androgens helps in the maintenance of body fluid volume and osmotic pressure only.

Answer

To solve the question regarding adrenal hormones, we will analyze each statement provided and determine which one is correct.

### Step-by-Step Solution:

1. **Statement Analysis**:
- **Statement 1**: "Aldosterone stimulates the reabsorption of calcium and water from renal tubule."
- **Analysis**: Aldosterone primarily stimulates the reabsorption of sodium and water, not calcium. It does influence potassium and indirectly affects calcium levels, but it is not the primary hormone for calcium reabsorption.

- **Statement 2**: "Cortisol is a major glucocorticoid."
- **Analysis**: This statement is correct. Cortisol is indeed the primary glucocorticoid produced by the adrenal cortex and plays a significant role in metabolism, particularly in increasing blood sugar levels during stress.

- **Statement 3**: "Glucocorticoid promotes cellular uptake and utilization of amino acid."
- **Analysis**: While glucocorticoids can influence amino acid metabolism, they do not primarily promote uptake; instead, they can lead to the breakdown of proteins to release amino acids into the bloodstream.

- **Statement 4**: "Androgen helps in maintaining body fluid and volume."
- **Analysis**: Androgens are primarily involved in the development of male characteristics and reproductive functions, not directly in maintaining body fluid and volume. This statement is misleading.

2. **Conclusion**:
- Based on the analysis, the only correct statement is Statement 2: "Cortisol is a major glucocorticoid."

### Final Answer:
The correct statement about adrenal hormones is **Statement 2: Cortisol is a major glucocorticoid.**
