The correct Answer is:

### Step-by-Step Solution: 1. **Identify the Hormone**: The question asks about the function of thyrocalcitonin, also known as calcitonin (TCT). 2. **Source of the Hormone**: Thyrocalcitonin is secreted by the thyroid gland, which is located on either side of the trachea. 3. **Type of Hormone**: It is classified as a peptide hormone, which means it is made up of amino acids. 4. **Function of Thyrocalcitonin**: The primary function of thyrocalcitonin is to regulate calcium levels in the blood. 5. **Mechanism of Action**: Thyrocalcitonin works to decrease the calcium levels in the blood. It does this by promoting the deposition of calcium in the bones, thus facilitating bone formation. 6. **Evaluate the Options**: Given the options: - Option A: Reduce the calcium level in blood (Correct) - Option B: Increase the calcium level in blood - Option C: Oppose the action of thyroxine - Option D: Maturation of gonads 7. **Conclusion**: The correct answer is Option A, as thyrocalcitonin functions to reduce the calcium level in the blood.

Thyrocalcitonin is secreted during

Increased blood calcium level

Decreased blood calcium level

Both A and B

Increased blood sugar level

Assertion :- Parathormone & thyrocalcitonin are antagonist to each other. Reason:- Parathormone maintains Ca^(+2) concen tration in blood and it's receptors are present in osteoclast cells.

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false.

Assertion :- Thyrocalcitonin & Parathormone have antagonistic effect on blood calcium level. Reason:- Thyrocalcitonin lower the blood calcium level and parathorrnone raises the blood calcium level by removal of calcium from bone and reabsorption of calcium from nephrons.
