B Correct answer
Explanation

Beta decay involves a neutron converting to a proton (emitting an electron and antineutrino). This increases the atomic number by 1 (more protons) but mass number stays nearly the same (proton+neutron count unchanged). Option A describes neither decay type. Option C describes alpha decay. Option D is incorrect.
