What completes an electric circuit safely?

• A. Grounding
• B. GFI
• C. Fuse
• D. Anode

Answer: (A)

Grounding provides a direct path for fault current to the earth, keeping exposed parts at a safe, near-zero potential and allowing protective devices to interrupt power quickly. In a fault, this safe return path is what makes the circuit safe by preventing shock. The other options play different safety roles—ground fault interrupters detect leakage and cut power, fuses blow to stop overloads, and an anode isn’t related to completing a safe fault path.
