    not possible as proton mass is less than the neutron mass
  • possible only inside the nucleus
  • C
    not possible but neutron to proton conversion is possible
  • D
    always possible as it is associated only with $\beta^{+}$ decay

Answer

Correct option: B.
possible only inside the nucleus
b
It is possible only inside the nucleus and not otherwise.
