Interphone code 21 is used to call the flight deck?

Explanation:
Interphone systems route calls to specific areas of the aircraft. When you need to speak with the pilots, you use the interphone to place a call directly to the flight deck. This is different from issuing a public address to the main cabin, which is just a passenger announcement, or an emergency call to all stations, which is a broad alert. It also isn’t a call to the forward cabin crew. So the action that directly connects you to the pilots is to call the flight deck, which is why this option is the correct choice.
