Answer :
Final answer:
The first two men to ride in a lighter-than-air craft were the Montgolfier brothers, who conducted the first manned hot air balloon flight in 1783. The Wright brothers were responsible for the first powered airplane flight in 1903, in the field of heavier-than-air craft.Hence option A is correct.
Explanation:
The first two men to ride in a lighter-than-air craft were the Montgolfier brothers, namely Joseph-Michel and Jacques-Étienne Montgolfier, who are celebrated for pioneering hot air balloon flight. Their first manned hot air balloon flight took place in 1783 and marked the advent of human flight.
The Wright brothers, Orville and Wilbur, on the other hand, are famous for achieving the first powered airplane flight in 1903, which was an entirely different domain of aeronautics, focusing on heavier-than-air craft. While the Montgolfier brothers and Wright brothers were both critical to the development of aviation, their contributions were distinct and in different periods of the history of flight.
