Consider the following statements about the bridge measurement:
1. The measurement accuracy is directly related to the accuracy of the bridge component as well as that of the null indicator used.
2. The basic dc bridge used for accurate measurement of resistance is called Wheatstone’s bridge.
3. When the bridge is in balanced condition, current flows through the galvanometer, causing a deflection of its pointer.
4. A more sensitive galvanometer deflects by a greater amount for the same current.
5. The sensitivity of the bridge measurement can only be expressed in mm/μA.

Analysis of Statements on Bridge Measurement
When evaluating the given statements about bridge measurement, we can break down each statement to determine its correctness.
1. Measurement Accuracy
- The accuracy of bridge measurements indeed depends on both the bridge components and the null indicator.
- Therefore, this statement is correct.
2. Basic DC Bridge
- The Wheatstone bridge is the fundamental circuit used for the precise measurement of resistance.
- This statement is correct.
3. Balanced Condition and Galvanometer
- In a balanced condition, no current flows through the galvanometer, which indicates that the resistance values are equal.
- Thus, this statement is incorrect.
4. Sensitivity of Galvanometer
- A more sensitive galvanometer will indeed show greater deflection for the same amount of current, which is a fundamental property of such instruments.
- This statement is correct.
5. Sensitivity Expression
- Sensitivity can be expressed in various units, not just mm/μA. This statement is too restrictive.
- Therefore, this statement is incorrect.
Conclusion
Given the analysis:
- Correct Statements: 1, 2, and 4
- Incorrect Statements: 3 and 5
Thus, the only statements that are correct are 2 and 4, which corresponds to option 'C'.
