Options

B. adrenaline
C. growth hormone
D. thyroxin hormone

Answer

**Step-by-Step Solution:**

1. **Understanding Dwarfism**: Dwarfism is a condition where an individual does not reach the average height for their age and sex. It is classified as a deficiency disorder.

2. **Identifying the Cause**: To determine the cause of dwarfism, we need to look at the hormones that are involved in growth and development.

3. **Analyzing Hormones**:
- **Insulin Hormone**: This hormone is produced by the pancreas and regulates blood glucose levels. It is not directly related to growth in height.
- **Adrenaline Hormone**: Secreted by the adrenal glands, adrenaline is known as the "fight or flight" hormone and is involved in emergency responses. It does not play a role in growth.
- **Growth Hormone**: This hormone is crucial for growth and development. It is produced by the pituitary gland. A deficiency in growth hormone leads to reduced growth and can result in dwarfism.
- **Thyroxine Hormone**: Produced by the thyroid gland, thyroxine regulates metabolism but is not the primary hormone responsible for height growth.

4. **Conclusion**: The hormone that, when deficient, leads to dwarfism is the growth hormone. Therefore, dwarfism occurs due to the deficiency of the growth hormone.

5. **Final Answer**: Dwarfism occurs due to the deficiency of the growth hormone.
