If the compressor clutch relay is stuck closed, it will keep sending power to the compressor clutch even when the A/C switch is turned off. This will cause the clutch to remain engaged and result in the compressor continuing to run, even when it should be off. The other options may also cause issues with the A/C system, but they are less likely to cause the specific symptom described in this scenario.
