Best answer
Correct answer is (b) Arc carter

Best explanation: Depth of fusion is defined as the depth to which the metal is melted and deposited. The molten metal is forced out of the pool by an electric arc, which forms a small depression in the parent metal where the molten metal is piled up. This is known as arc carter. The distance between the tip of the electrode and the bottom of the arc crater is called arc length.
