Circuit requires diagram for equivalent resistance calculation Steps:

• Identify series and parallel combinations from the circuit diagram.
• Calculate parallel resistances using 1/R_eq = 1/R1 + 1/R2.
• Add series resistances: R_eq = R1 + R2 + ...
• Not enough information: No circuit diagram provided to determine configuration.

Why C is correct:

• Not applicable without diagram; C assumes a specific setup yielding 6.0 Ω total.

Why the others are wrong:

• A: Would require all resistors in parallel, but unconfirmed.
• B: Possible for partial parallel-series mix, but unconfirmed.
• D: Suggests all in series, but unconfirmed.

Final answer: Not enough information.
