AI Explanation
The correct answer is D) sheave.
The grooved wheel inside a block is called a sheave. This is the standard term used in maritime and nautical contexts to refer to the grooved wheel that a rope or cable runs through inside a block or pulley system. The sheave is designed to reduce friction and wear on the rope or cable as it passes through the block.
The other answer choices are not the correct term for this component. A cheek refers to the side plates of a block, a gypsy is a type of winch, and a drum typically refers to the barrel of a winch or windlass. None of these terms accurately describe the grooved wheel inside a block.
