technician a says that there are two kinds of brake rotors, hub and hubless. technician b says all brake rotors are vented. who is correct?
technician a
technician b
both technician a and technician b are correct
neither technician is correct

Explanation:

Brake rotors have two main types: hub (where the rotor has an integral hub) and hubless (floating rotors, separate from the hub). So Technician A is correct. Technician B is wrong because not all brake rotors are vented (some are solid). Thus, only Technician A's statement is correct.

A. Technician A
