Errors and Accuracy in Measurements

Consider the given statements:
Statement A: Measured value by any measuring instrument has some error.
Statement B: A measurement can have more accuracy and less precision and vice-versa.
Statement C: The magnitude of the difference between the true value of the quantity and the individual measured value is called relative error of measurement.
Choose the correct option.
Only statement A is true
Only statement B is true
Both statements A and C are true
Both statements A and B are true

Solution:

Statements A and B are correct properties of measurements. Statement C is incorrect because the described quantity is the absolute error, not the relative error.
