$\text{Hint: Recall the order of the electromagnetic spectrum.}$ $\text{Explanation: Electromagnetic (EM) waves cover a wide range of wavelengths, from very long (like radio waves) to very short (like gamma rays).}$ $\text{The different types of EM waves are categorized based on their wavelength and frequency.}$ $\text{Ultraviolet rays (UV rays): These have wavelengths in the range of 10 nm to 400 nm.}$ $X\text{-rays: X-rays have wavelengths between 0.01 nm and 10 nm.}$ $\text{Gamma-rays: These have the shortest wavelengths, typically less than 0.01 nm, and can go down to picometer (pm) or even smaller wavelengths.}$ $\text{Gamma rays are produced by nuclear reactions and are highly energetic.}$ $\text{Microwaves: These have wavelengths ranging from 1 mm, to 30 cm, which are much longer than UV rays, X-rays, and gamma rays.}$ $\text{Therefore, gamma rays have the shortest wavelengths in the electromagnetic spectrum and the highest energy, which is why they are classified as the most penetrating and dangerous form of electromagnetic radiation.}$ $\text{Hence, option (3) is the correct answer.}$
