What is the aircraft identifier for the Devellin Hand-8?

The aircraft identifier for the Devellin Hand-8 is correctly represented by the option DH8A. This identifier is structured according to the International Civil Aviation Organization (ICAO) standards, which define specific codes for aircraft types. The "DH" prefix indicates that the aircraft is from DeHavilland, and the "8" signifies the specific model within that manufacturer's series. The "A" suffix denotes a particular variant of the aircraft.

Identifiers in aviation are often used to facilitate air traffic control, flight planning, and communication, so having a unique code for each aircraft helps in identifying them unambiguously in air traffic systems. The other options do not conform to the established ICAO naming conventions for the Devellin Hand-8, thus making them unsuitable as identifiers for this specific aircraft model.
