Correct answer: B

Identify the standard sources of each electromagnetic radiation
- Microwaves are commonly produced by a magnetron.
- Infrared waves are emitted due to vibrations of atoms and molecules.
- Gamma rays originate from radioactive decay of the nucleus.
- X-rays are produced when inner shell electrons undergo transitions or due to high-speed electron bombardment.
Match List I with List II
$(a)\ \text{Source of microwave frequency} \rightarrow (ii)\ \text{Magnetron}$ $(b)\ \text{Source of infrared frequency} \rightarrow (iv)\ \text{Vibration of atoms and molecules}$ $(c)\ \text{Source of Gamma Rays} \rightarrow (i)\ \text{Radioactive decay of nucleus}$ $(d)\ \text{Source of X-rays} \rightarrow (iii)\ \text{Inner shell electrons}$
Compare with the given options

The matching obtained is:
$(a)-(ii),\ (b)-(iv),\ (c)-(i),\ (d)-(iii)$
This corresponds to Option B.
