A. Microwave $\to$ IV

Microwaves have short wavelength hence low energy dispersion during long distance communication. Thus, they are used in radar system.
B. UV rays $\to$ III

LASIK uses an excimer laser (an ultraviolet laser) to remove a thin layer of corneal tissue.

C. Infra-red $\to$I

Infrared radiation in the device called infrared lamp is used in physiotherapy. This light is useful in reducing pain, decreasing inflammation, and speeding up wound care and tissue repair.

D. $\mathrm{X}$-ray $\to$ II

Radiation therapy uses high-energy particles or waves, such as x-rays to destroy or damage cancer cells.
