The question asks for the equivalent resistance of a network, but the circuit diagram/network itself is not provided in the prompt.

Without the actual resistor arrangement, the equivalent resistance cannot be determined uniquely.

What can be concluded

1. The problem statement is incomplete because the resistor network image/description is missing.
2. Therefore, no valid step-by-step numerical calculation can be performed.
3. Since the stored correct answer is given as $1\,\Omega$, I cannot independently verify it without the circuit.

Required to solve

Please provide either:

• the circuit diagram, or
• a textual description of how the resistors are connected and their values.

Then I can compute the equivalent resistance step-by-step.
