Answer 1

Radar was the technological advance from World War II that observed and collected information on aircraft movement, playing a crucial role in defending against enemy attacks. The correct option is c. Radar

Step-by-step explanation:

The technological advance from World War II that fulfilled the mission to "observe the movement of aircraft and to collect and exhibit the information obtained" was radar.

Radar was used effectively during the war to provide advance warning of enemy attacks, particularly during the Battle of Britain and in the North Atlantic to counter German U-Boat threats.

Its development in the 1930s and perfection by the early 1940s played a crucial role in defending nations against enemy aircraft and determining the outcome of significant battle engagements. The correct option is c. Radar
