p. s "both"is wrong

C is correct i believe i think all the others are wrong but im not entirely sure

The correct answer is option C. "Technician A only".

Explanation:

Technician A was right by saying that the oil control ring scrapes oil off the cylinder wall with each downward piston stroke. Actually, that is the main function of the oil control ring, to wipe out the excess oil that is produced during piston movement.

Technician B was wrong by saying that a typical oil control ring consists of two separate pieces. A typical oil control is comprised of three separate pieces: two scrappers and a expander.
