Detailed explanation-1: -Abhishek Mishra. Option C Solution: There have been several rigid-wing hang gliders flown since Otto Lilienthal took his first flights in the 1890s. The first two high-performing modern hang gliders, however, were the Mitchell Wing and the Icarus.

Detailed explanation-2: -Hang gliders were developed by the pioneers of practical flight. In Germany, starting in 1891, Otto Lilienthal made several thousand flights before a fatal gliding accident in 1896. He published plans of his gliders and even supplied kits.
