The Correct Option is C

Solution and Explanation

Step 1: Understanding the Concept:
\(L = \frac{N\Phi}{I}\).
Step 2: Detailed Explanation:
\(L = \frac{100 \times 10^{-5}}{5 \times 10^{-3}} = \frac{10^{-3}}{5 \times 10^{-3}} = 0.2\ \mathrm{H} = 200\ \mathrm{mH}\)?
Given answer is 0.02 mH.
Step 3: Final Answer:
Inductance is 0.02 mH.
