A tool consisting of a handle and releasable chain used for turning pipe or fittings of a diameter larger than that which a pipe wrench would fit is called __________.

Correct Answer: Option B — chain tongs

Chain tongs are manual tools consisting of a handle and a heavy-duty chain. They are specifically designed to grip and rotate large-diameter pipes or fittings where standard pipe wrenches are insufficient. The chain wraps around the circumference, providing the necessary leverage for makeup or breakout operations.
