The hormone which produces calorigenic effect in the body is

Options

A. Adrenaline
B. FSH
C. Growth hormone
D. Thyroxine

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the hormone that produces a calorigenic effect in the body. The calorigenic effect refers to the increase in metabolic rate and heat production in the body.

2. **Identifying the Options**: The options provided are:
- Option 1: Adrenaline
- Option 2: FSH (Follicle Stimulating Hormone)
- Option 3: Growth Hormone
- Option 4: Thyroxine Hormone

3. **Analyzing Each Option**:
- **Adrenaline**: This hormone is released from the adrenal medulla and is known as an emergency hormone. It increases heart rate and blood pressure but does not primarily regulate metabolic rate.
- **FSH**: Follicle Stimulating Hormone is produced by the anterior pituitary gland and is involved in the maturation of reproductive cells, not in metabolic regulation.
- **Growth Hormone**: Also released from the anterior pituitary, it is responsible for growth and development but does not have a direct calorigenic effect.
- **Thyroxine Hormone**: This hormone is produced by the thyroid gland and is known to regulate the basal metabolic rate (BMR). It increases the overall metabolic activity in the body, leading to a calorigenic effect.

4. **Conclusion**: Based on the analysis, the hormone that produces a calorigenic effect in the body is **Thyroxine Hormone** (Option 4).

5. **Final Answer**: The correct answer is **Thyroxine Hormone**.
