Solution

The correct option is B X-rays > UV rays > Microwaves > Radio waves
X-rays have frequencies in the range of $10^{16}$ to $10^{20}$ Hz.
UV rays have frequencies in the range of $10^{14}$ to $10^{16}$ Hz.
Microwaves have frequencies in the range of $10^{8}$ to $10^{10}$ Hz.
Radio waves have frequencies in the range of $10^{4}$ to $10^{8}$ Hz.
Hence, the correct option is (b).
