Choose the correct option

Options

A. Accurate measurement is necessary.
B. Estimation is necessary.
C. Both (a) and (b) depending upon the situation.
D. Neither (a) nor (b).

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks to choose the correct option regarding measurements and their accuracy in different situations.

2. **Analyzing the Options**:
- **Option 1**: "Accurate measurement is negative" - This statement does not make sense in the context of measurement.
- **Option 2**: "Accurate measurement is necessary" - This statement is true when precise measurements are required, such as measuring human body temperature.
- **Option 3**: "Both A and B depending upon the situation" - This suggests that both accurate measurement and estimation are important based on the context.
- **Option 4**: "Neither A nor B" - This implies that neither of the previous statements is correct.

3. **Evaluating Each Option**:
- **Option 1** is incorrect as accurate measurement is essential in many scenarios.
- **Option 2** is correct in situations where precision is crucial, like medical measurements.
- **Option 3** is also correct because it acknowledges that both accurate measurement and estimation can be important depending on the context (e.g., precise measurements for health vs. estimations for construction).
- **Option 4** is incorrect because at least one of the previous options is valid.

4. **Conclusion**: After evaluating the options, **Option 3** is the most appropriate choice since it recognizes the importance of both accurate measurement and estimation depending on the situation.

5. **Final Answer**: The correct option is **Option 3**.
