    Answer: D

    Neither A nor B

    Explanation:

    In order to check the clearances for rod and main bearings, you need a set of micrometers and a dial-bore gauge

    Measuring the inside diameter of a main or rod bearing will require a dial bore gauge. The best ones to use are accurate down to 0.0001-inch.

    So, both technician A and B are incorrect
