We can simplify the circuit by combining the two parallel resistors (6 Ω and 8 Ω) to get a total resistance of 3.43 Ω (using the formula R_total = R1 × R2 / (R1 + R2)). Then, we can combine this with the 2 Ω resistor in series to get a total resistance of 5.43 Ω. Finally, we can combine this with the remaining 14 Ω resistor in series to get a total resistance of 19.43 Ω. Therefore, the equivalent resistance of the circuit is 19.43 Ω, which is closest to answer choice C) 392 Ω.
