What is the actual height above mean sea level at which the aircraft is flying?

Explanation:
Height above mean sea level is described by altitude. The altimeter is the instrument that measures and displays this height by sensing ambient pressure, but the actual height you’re flying at is called altitude (MSL). The other options don’t fit because airworthiness is a certification, and an alternate static source is just a backup pressure source for the instrument, not the height itself.
