What is hysteresis in an instrument?
A. The difference between the maximum and minimum values that can be measured by the instrument.
B. The degree of change in the output signal for a given change in the input signal.
C. The tendency of an instrument to give different readings for the same input signal when approached from different directions.
D. The degree of closeness of the measured value to the true value of the signal.

The degree of closeness of the measured value to the true value of the signal.
Explanation: Hysteresis is a characteristic of an instrument that refers to the tendency of the instrument to give different readings for the same input signal when approached from different directions. This can occur due to changes in the material properties of the instrument or due to the presence of internal friction.
