Answer: A → I, B → II, C → III, D → IV
Solution
Infrared radiation carries heat, so it is the part of the spectrum used to relieve muscular strain. Radio waves are the long-wavelength waves broadcast for radio and television. X-rays pass through soft tissue but are stopped by bone, which is why they reveal fractures. Ultraviolet rays are the ones absorbed by the ozone layer, which shields us from their harmful effect. So infrared goes with muscular strain, radio with broadcasting, X-rays with detecting fractures, and ultraviolet with absorption by the ozone layer.
