$$1 - iv,\,\,2 - iii,\,\,3 - ii,\,\,4 - i$$
$$1 - i,\,\,2 - ii,\,\,3 - iv,\,\,4 - iii$$
$$1 - iii,\,\,2 - ii,\,\,3 - i,\,\,4 - iv$$
$$1 - i,\,\,2 - ii,\,\,3 - iii,\,\,4 - iv$$
Explanation
$$\left( 1 \right)\,\,\,\,\,\,$$ Infrared rays are used to treat muscular strain because these are heat rays.
$$\left( 2 \right)\,\,\,\,\,\,$$ Radio waves are used for broadcasting because these waves have very long wavelength runging from few centimeters to few hundred kilometers
$$\left( 3 \right)\,\,\,\,\,\,$$ $$X$$-rays are used to detect fracture of bones because they have high penetrating power but they can't penetrate through denser medium like bones.
$$\left( 4 \right)\,\,\,\,\,\,$$ Ultraviolet rays are absorbed by ozone of the atmosphere.
