The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Dwarfism**: Dwarfism is a medical condition characterized by short stature, typically resulting from genetic or hormonal factors. 2. **Role of Growth Hormone**: The growth hormone (GH) is crucial for growth and development in children. It is secreted by the pituitary gland and stimulates growth in various tissues, including bones. 3. **Cause of Dwarfism**: Dwarfism is primarily caused by a deficiency of the growth hormone during childhood. When the body does not produce enough growth hormone, it leads to stunted growth and shorter height. 4. **Differentiating Hormonal Effects**: - Excess secretion of growth hormone leads to gigantism, which is characterized by excessive growth. - Thyroxine, produced by the thyroid gland, is not directly related to dwarfism. - Adrenaline, produced by the adrenal glands, does not influence height and is not a factor in dwarfism. 5. **Conclusion**: The correct answer to the question of what causes dwarfism is the "less secretion of the growth hormone." **Final Answer**: Dwarfism results due to the deficiency of the growth hormone. ---
