Answer: (C)

Frank Whittle is best known for inventing the jet engine, which marked a revolutionary advancement in aviation technology. His design utilized a turbojet engine, allowing aircraft to fly faster and higher than ever before. The innovation brought by Whittle in the early 1930s significantly transformed military and commercial aviation by enabling faster travel and new capabilities that were previously unattainable with piston engines. The effectiveness and efficiency of jet engines have led to their widespread adoption in modern aircraft, making his contribution a pivotal moment in aviation history.

While electric aircraft, turbine engines, and advanced radar systems are important innovations, they do not directly relate to Whittle's groundbreaking work on the jet engine, which is the correct answer. His pioneering developments laid the foundation for the jet age, changing the landscape of air travel forever.
