C Correct answer
Explanation

In beta decay, a neutrino (or antineutrino) is always emitted along with the beta particle. In beta-minus decay, an antineutrino is emitted; in beta-plus decay, a neutrino is emitted. This conserves lepton number and accounts for the continuous energy spectrum of beta particles.
