B) Speed of electron
C) Speed of d-particles
D) Speed of light and gamma rays ​

Answer 1

X rays are light waves (electromagnetic waves). So they travel at 299792458 metres per second (approximately 3.00×10^8 m/s) in vacuum and reduce according to the refractive index of the medium in other media.

Answer 2

Answer:

answer is (d) speed of light and gamma rays
