UPSC CSE Prelims 2006

Correct Option (A):

The pairs are correctly matched as follows:

• Christopher Cockerell is credited with the invention of the hovercraft. He developed the first practical hovercraft in the 1950s, with its official launch occurring in 1959.
• David Bushnell invented the Turtle, which is recognized as the first military submarine. It was utilized during the American Revolutionary War (1775–1783).
• J. C. Perrier pioneered steam-powered navigation by inventing an early steamship in 1775.

Therefore, all three pairs are correctly matched.

Incorrect Options:

Options B, C, and D are incorrect because they exclude one or more of the correctly matched pairs. Since all three pairs (1, 2, and 3) are factually accurate, any option that does not include all of them is incorrect.
