Correct Answer - A::C
Emission of gamma radiations involves emission of energy only . i. e. transition between energy levels within the nucleus.
`._(1)H^(3) rarr -(2)He^(3)+ _(-1)e^(0)`
During position decay, a proton gets converted into a neutron & a positron
`._(1)P^(1) rarr ._(0)n^(1) +._(1)e^(0)`
So `(n)/(P)` ratio increases
