Among the following the error that can be eliminated is

Options

A. Systematic error
B. Random errror
C. Gross error
D. None

Answer

To solve the question regarding which type of error can be eliminated, we will analyze the different types of errors mentioned in the options: systematic error, random error, gross error, and none.

### Step-by-Step Solution:

1. **Understanding Systematic Errors**:
Systematic errors arise from consistent and repeatable faults in the measurement process. These could be due to improperly calibrated instruments or consistent biases in measurement techniques. Since systematic errors are predictable and consistent, they can be identified and corrected by recalibrating the instruments or adjusting the measurement process.

**Hint**: Look for errors that can be corrected through calibration or adjustment.

2. **Understanding Random Errors**:
Random errors are caused by unpredictable variations in the measurement process. They can occur due to fluctuations in environmental conditions, human error, or limitations in the measuring instrument. While random errors can be minimized through repeated measurements and statistical analysis, they cannot be completely eliminated.

**Hint**: Consider whether the error is due to random fluctuations that cannot be controlled.

3. **Understanding Gross Errors**:
Gross errors are significant mistakes that occur during the measurement process, often due to human error, such as misreading an instrument or recording data incorrectly. These errors can sometimes be identified and corrected, but they are not systematic in nature.

**Hint**: Think about errors that are due to obvious mistakes rather than consistent patterns.

4. **Conclusion**:
Among the types of errors discussed, systematic errors are the only ones that can be eliminated through proper calibration and correction of the measuring instruments. Random errors and gross errors cannot be completely eliminated, as random errors are inherently unpredictable, and gross errors are often due to human mistakes.

Therefore, the correct answer is **systematic error**.

### Final Answer:
The error that can be eliminated is **systematic error**.
