AI Explanation

The correct answer is A) thimble. The rotating part of a micrometer, which is used to measure small distances with high precision, is known as the thimble. The thimble is the knurled (grooved) part that you turn to move the spindle and take a measurement. The other options are incorrect - the anvil is the stationary part that the object being measured rests against, the sleeve is the cylindrical body of the micrometer, and the frame is the overall structure that holds the other components.
