Read the statement given below. Identify which of them are true and which of them are false. Select the correct option after referring to the given table.
A. The pituitary gland is present in a bony cavity of the skull known as sella tursica.
B. The pancreas is only an endocrine gland.
C. The diurnal rhythm of the body is maintained by the pineal gland.
D. Glucocorticoids stimulate glycolysis, lipolysis and proteolysis.

Options

A. A - True, B - False, C - True, D - False
B. A - False, B - True, C - False, D - True
C. A - True, B - False, C - True, D - True
D. A - False, B -True, C - True, D - True

Answer

To solve the question, we will evaluate each statement one by one to determine whether they are true or false.

### Step-by-Step Solution:

1. **Statement A**: "The pituitary gland is present in a bony cavity of the skull known as sella turcica."
- **Evaluation**: This statement is **true**. The pituitary gland is indeed located in a bony cavity at the base of the skull called the sella turcica, which is part of the sphenoid bone.

2. **Statement B**: "The pancreas is only an endocrine gland."
- **Evaluation**: This statement is **false**. The pancreas functions as both an endocrine gland (secreting hormones like insulin and glucagon) and an exocrine gland (producing digestive enzymes).

3. **Statement C**: "The diurnal rhythm of the body is maintained by the pineal gland."
- **Evaluation**: This statement is **true**. The pineal gland produces melatonin, which helps regulate the sleep-wake cycle and thus maintains the diurnal rhythm.

4. **Statement D**: "Glucocorticoids stimulate glycolysis, lipolysis, and proteolysis."
- **Evaluation**: This statement is **false**. Glucocorticoids primarily promote gluconeogenesis (the formation of glucose from non-carbohydrate sources) rather than glycolysis. They also influence lipid and protein metabolism but do not directly stimulate glycolysis.

### Summary of Evaluations:
- Statement A: **True**
- Statement B: **False**
- Statement C: **True**
- Statement D: **False**

### Final Answer:
The correct evaluations are:
- A: True
- B: False
- C: True
- D: False
