Growth through increase in volume is

Options

A. Cartilage
B. Striated muscle
C. Nerve fibre
D. Lens of eye

Answer

To solve the question "Growth through increase in volume is," we need to analyze the options provided and understand the characteristics of each.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the type of growth that occurs through an increase in volume. This means we are looking for a biological structure that grows by expanding its size rather than just increasing in length or thickness.

2. **Analyze the Options**:
- **Option A: Cartilage**: Cartilage is a flexible connective tissue found in various parts of the body, such as the ear and joints. Its growth is typically measured by an increase in thickness rather than volume. Therefore, this option is incorrect.

- **Option B: Striated Muscle**: Striated muscles, also known as skeletal muscles, are responsible for voluntary movements. They grow primarily by increasing their volume through the addition of muscle fibers and the hypertrophy of existing fibers. This option aligns with the question, making it a strong candidate.

- **Option C: Nerve Fiber**: Nerve fibers primarily grow by increasing in length rather than volume. Thus, this option is also incorrect.

- **Option D: Lens of the Eye**: The lens of the eye grows by increasing its diameter, not its volume. Therefore, this option is also incorrect.

3. **Conclusion**: After analyzing all the options, we find that the only structure that grows through an increase in volume is **Option B: Striated Muscle**.

### Final Answer:
The correct answer is **Striated Muscle**.
