To which country was Dahl sent to complete the last part of his training?

Dahl was sent to Habbaniya, which is located in Iraq, to complete the last part of his training. This choice reflects an important phase in his journey as a pilot during World War II. Habbaniya served as a British Royal Air Force base during the war, and it was where Dahl gained valuable experience and skills that would later contribute to his career as a fighter pilot.

In the context of the other options, while Egypt, India, and South Africa were significant locations during the war and relevant to various aspects of military training and activity, they do not specifically relate to the final stages of Dahl's training as a pilot. Habbaniya is the correct answer because it aligns precisely with the historical details concerning Dahl's military training background.
