The Correct Option is D

Solution and Explanation

Step 1: Understanding the Concept:
Colour code: Black(0), Brown(1), Red(2), Orange(3), Yellow(4), Green(5), Blue(6), Violet(7), Grey(8), White(9).
Step 2: Detailed Explanation:
The colour bands are White, Brown, Red, Silver. White = 9, Brown = 1, Red = $10^2$, Silver = $\pm 10%$. So resistance = $91 \times 10^2 = 9100\Omega = 9.1\mathrm{k}\Omega$.
Step 3: Final Answer:
The resistance is $9.1\mathrm{k}\Omega$.
