Which helicopter uses the GAU-21 .50Cal as part of its armament?

Explanation:
The key idea is that the GAU-21 .50 cal is a door-gun setup used on certain Marine helicopters for close fire support. The Venom UH-1Y is configured with a door-mounted GAU-21 .50 cal, giving it a reliable fixed forward-firing capability to engage threats from the aircraft’s side door during low-altitude flight. The other helicopters listed use different armaments by default—an AH-1W Super Cobra relies on a 20mm cannon for its primary armament, the MV-22B is a transport tiltrotor with limited standard door-gun capability, and the CH-53E uses other defensive/armament configurations rather than the GAU-21. Therefore, the UH-1Y Venom is the platform that includes the GAU-21 .50 cal.
