C.γ-rays
D.neutron
Explanation & Solution

Correct Answer: (B) β-particle

In the given nuclear reaction, Neptunium (93Np239_{93}Np\text{Np}Np^{239}93​Np239) transforms into Plutonium (94Pu239_{94}Pu\text{Pu}Pu^{239}94​Pu239) while the mass number remains unchanged and the atomic number increases by 1, which corresponds to the emission of a beta particle.
