Hi there! Your mouth can take in oxygen, so A is out. Your nose cleans the air you breathe, and gets rid of foreign particles (dust, pollen, etc), which is why you sneeze to get those things out. Breaking down oxygen doesn’t make any sense. The answer is B.
Correct option:
Beta particles are identical to "electrons".
What are particle beams:
There are various types of particle beams, such as (alpha) and (beta) particles, neutron beams, etc. While β-particles are electrons released from a nucleus, helium nuclei made up of two protons and two neutrons are known as α-particles.
When certain radionuclides undergo a process known as beta-decay, high-energy, high-speed electrons (e-) or positrons (p+) are released from the nucleus.
An electron and a beta particle share the same mass and charge.
Beta radiation in high doses can burn the skin, and beta emitters are dangerous if they penetrate the body. Thin sheets of metal or plastic may be able to stop beta particles.
Note: Your question is incomplete, but most probably your full question also includes one more option "Electron".
