Metamorphosis is studied under

Options

A. Neurology
B. Embryology
C. Cardiology
D. Physiology.

Answer

**Step-by-Step Solution:**

1. **Understanding Metamorphosis**: Metamorphosis refers to the process by which certain animals undergo significant physical changes after birth, transitioning from an immature form (like an egg or larva) to an adult form.

2. **Identifying Relevant Fields of Study**: To determine where metamorphosis is studied, we need to look at the options provided:
- **Neurology**: This is the study of the nervous system and neurons.
- **Embryology**: This is the study of the development of embryos and fetuses.
- **Cardiology**: This is the study of the heart and its functions.
- **Physiology**: This is the study of the functions of living organisms and their parts.

3. **Analyzing Each Option**:
- **Neurology**: Not relevant, as it focuses on the nervous system.
- **Embryology**: Relevant, as it deals with the development processes that include metamorphosis.
- **Cardiology**: Not relevant, as it focuses on the heart.
- **Physiology**: While it studies functions, it does not specifically focus on the developmental changes associated with metamorphosis.

4. **Conclusion**: Since metamorphosis involves the development of an organism from an embryo to its adult form, it is most appropriately studied under embryology.

5. **Final Answer**: The correct option is **embryology**.
