C
0.1%
D
20%
Answer Notes
Resistor tolerance indicates how far the actual resistance might deviate from its stated, or nominal, value. A lower percentage means the actual value is guaranteed to be closer to the stated value, which means it is more precise.
Therefore, 0.1% represents the narrowest margin of error and the highest precision among the choices provided. The other options (5%, 10%, 20%) all allow for much wider variations and are generally used in less critical circuits.
