D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Growth**: Growth refers to the process by which an organism increases in size, weight, or the number of cells. It is a fundamental characteristic of living organisms.

2. **Analyzing the Options**:
- **Option 1: Increase in size**: This is a clear indication of growth. When an organism grows, its size typically increases. For example, a seedling growing into a plant shows an increase in size.

- **Option 2: Increase in weight**: This is also a valid aspect of growth. As an organism increases in size, its weight usually increases as well. For instance, as a child grows, they gain weight along with height.

- **Option 3: Synthesis of new protoplasm**: Growth involves the synthesis of new cellular material, including protoplasm. As cells divide and multiply, new protoplasm is formed, contributing to the overall growth of the organism.

3. **Conclusion**: Since all three options (increase in size, increase in weight, and synthesis of new protoplasm) are valid indicators of growth, the correct answer to the question "Growth is" is **Option 4: All of these**.
