The Correct Option is C

Solution and Explanation

The equivalent resistance is calculated as follows:

\[ R_{\text{eq}} = \frac{15 \times 10}{15 + 10} = \frac{150}{25} = 6 \, \Omega \]

resistance
 Diode 2 is in reverse bias, so no current will flow through the branch containing it. It can be treated as a broken wire.

Diode 1 is in forward bias and will behave as a conducting wire. The new circuit becomes a simpler parallel and series resistor network.
