• A. It is a beam of electrons.
• B. It is electromagnetic waves.
• C. It is a positively charged particle.
• D. It is a negatively charged particle.

Answer 1

The correct option is B

It is electromagnetic waves.

Explanation for correct answer:

(B) X-rays are form of electromagnetic waves with wavelength of ${10}^{-9}\mathrm{m}$. Thus, it is an correct for X-rays.

Explanation for incorrect answer:

(A) X-rays are not comprising the beam of electrons. whereas, beam of electrons are produced in cathode rays. So, it is incorrect for X-rays.

(C) X-rays are neutral rays. These rays does not consists of charged particles. However, positively charged particles are present in alpha rays because these rays contains positively charged Helium nucleus. Thus, it is also incorrect for X-rays.

(D) Beta rays consists of negatively charged particles known as electrons. It is incorrect in case of X-rays.

Final answer:

Hence, the option (B) is correct.
