Answer: B

Explanation:

Correct Answer. B. Immediately turn off the power to the device before proceeding further Turning off the power immediately is the safest approach when dealing with exposed wiring, as it eliminates the risk of electrical shock, allowing for safe subsequent handling of the wiring issue.

Option A is incorrect because continuing to work near exposed wires without addressing the risk is unsafe.

Option C is incorrect as covering the wires with electrical tape does not address the potential hazard of the device being powered on.

Option D is incorrect because testing exposed wires while the device is powered could lead to electrical shock if the wires are live.
