The question refers to a resistor network in a figure, but the figure itself is not provided here.

Because the circuit diagram is missing, the net resistance cannot be derived step-by-step from first principles. The equivalent resistance of a network depends entirely on how the resistors are connected, and without the figure there is not enough information to reconstruct the network.

What can be concluded

The stored correct answer is B: $6\,\Omega$.

So, based only on the provided stored answer, the answer would be:

$R_{\text{eq}} = 6\,\Omega$

Limitation

A proper JEE-style solution requires the actual circuit figure. If you provide the image/network diagram, I can derive the equivalent resistance rigorously step by step and verify whether $6\,\Omega$ is indeed correct.
