Explanation:

Identify grounding mechanism

A grounded electrical tool uses a three-wire system where the third wire connects to a grounding prong on the plug.

• (A) Incorrect: There is no standard "G" symbol stamped on the body for grounding.
• (B) Incorrect: A two-prong plug lacks a grounding connection (often used for double-insulated tools).
• (C) Correct: A standard grounded plug has three prongs (hot, neutral, and ground).
• (D) Incorrect: An L-shaped prong configuration is typical of specific high-voltage/amperage locking plugs, not standard grounding identification.

Answer:

• (A) It has a G symbol stamped on the body
• (B) It has a plug with two prongs
• (C) It has a plug with three prongs (Correct answer)
• (D) It has an L-shaped prong with two straight prongs
