Both A and C.
Explanation:
Beta minus decay occurs when a neutron decays into a proton, electron, and antineutrino. So the atomic number increases by one.

C.
Explanation:
Let's say the radioactive isotope is Y and the new element formed is Z. If a beta particle (e) is released it would look something like this:
¹₀Y → ₋₁⁰e + ¹₁Z
So atomic number increases by 1 but mass number is unchanged.
