● Closeness with which an instrument reading approaches the true value is called accuracy.
● A measure of the reproducibility of the measurements is called precision.
● The ratio of output singal or response of the instrument to a change of input or measured variable is called sensitivity.
● The smallest change in measured value to which the instrument will respond is called Resolution.

Correct Option: A
