What is the type of feed for the Benelli M4 Super 90?

Explanation:
The best choice is rotating bolt. The Benelli M4 Super 90 uses a gas-operated system with a rotating locking bolt. After each shot, the gas drives the expanding gas and bolt carrier rearward, and a cam on the bolt rotates the bolt head to lock into the barrel extension. This rotating lockup provides a strong seal to contain the high pressure and then unlocks as the cycle continues to eject the spent shell and chamber the next one. The other options describe different ideas: a gas tappet is a different style gas system, semi-automatic refers to the firing mode rather than the locking/feeding mechanism, and bolt action denotes manual cycling with a non-rotating bolt.
