Options

A. metagenesis
B. metastasis
C. morphogenesis
D. metamorphosis

Answer

To solve the question "The process of transformation of larva into adult is called," we will analyze the options provided and determine the correct answer step by step.

### Step 1: Understand the Question
The question is asking for the specific term that describes the transformation process from a larval stage to an adult stage in an organism.

### Step 2: Analyze the Options
We have four options to consider:
1. **Metagenesis**
2. **Metastasis**
3. **Morphogenesis**
4. **Metamorphosis**

### Step 3: Evaluate Each Option
- **Metagenesis**: This term refers to the alteration of generations, which involves a switch between sexual and asexual reproduction. This does not specifically pertain to the transformation of larva into adult. Therefore, this option is incorrect.

- **Metastasis**: This term is related to the spread of cancer cells from one part of the body to another. It does not relate to the transformation of larva into adult. Thus, this option is also incorrect.

- **Morphogenesis**: This term refers to the development of form and structure in organisms, particularly concerning morphological characteristics. While it involves development, it does not specifically denote the transformation from larva to adult. Hence, this option is incorrect.

- **Metamorphosis**: This term specifically refers to the biological process where an organism undergoes a significant change in form from larva to adult. This is the correct term for the transformation process described in the question.

### Step 4: Conclusion
The correct answer to the question is **Metamorphosis**.
