If `400 Omega` of resistance is made by adding four `100 Omega` resistance of tolerance `5%`, then the tolerance of the combinations

Options

A. (a)0.2
B. (b)0.05
C. (c)0.1
D. (d)0.15

Explanation

To find the tolerance of the combination of resistors, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Each resistor has a resistance of \( R_1 = 100 \, \Omega \).
- The tolerance for each resistor is \( 5\% \).
