The correct answer is:

(b) zero drift

Zero drift refers to a change in the output of a measuring instrument over a specified period of time when the input is held constant, usually due to environmental factors such as temperature, humidity, or aging of the components. This drift causes the output to shift from its expected baseline (zero point) even though the input remains unchanged.
