Best answer
Correct answer is (d) Resolution

The best I can explain: Here, the meaning of noise is the effect on a signal due to surrounding electrical interference and magnetic fields. Noise is treated as a random Type-A uncertainty. Other random Type-A uncertainty with a normal distribution is thermal stability and repeatability.
