Answer:

C. 3325 Ω - 3675 Ω

Explanation:

5% of 3500 Ω is ...

0.05 × 3500 = 175

The lower limit is this amount less than the nominal value:

3500 -175 = 3325

The upper limit is the nominal value plus the tolerance:

3500 +175 = 3675

The lower and upper limits are 3325 Ω and 3675 Ω, respectively.
