Good Morning!

 
A) Beta particles are less energetic than alpha particles.

C) The beta particles are negatively charged;

D) Beta particles move much faster than alpha.

 -
B) The beta particles are smaller, so it is that they pass better.

 
hugs!

Answer: Option (B) is the correct answer.

Explanation:

Alpha particles are helium atoms whereas beta particles are just electrons. Electrons are much lighter than alpha particles (which include both protons and neutrons).

Therefore, electrons can move quickly from one place to other. Also, an electron or beta particle is 8,000 times smaller than alpha particle.

Hence, we can conclude that beta particles pass through materials more easily than alpha particles because beta particles are smaller.
