Correct Answer: Option B — the ohmic value would read very low and remain at that value

A shorted capacitor possesses an internal breakdown of its dielectric material, acting as a direct electrical conductor. When measured with an ohmmeter, the display immediately registers near-zero resistance and remains at that very low ohmic value indefinitely during troubleshooting.
