Final Answer :
B
Explanation :
The correct answer is B) 24He{ }_{2}^{4} \mathrm{He}24He , which represents an alpha particle. In nuclear reactions, the sum of mass numbers and the sum of atomic numbers must be equal on both sides of the equation. Here, 93237Np{ }_{93}^{237} \mathrm{Np}93237Np decays into 91233Pa{ }_{91}^{233} \mathrm{Pa}91233Pa and an alpha particle 24He{ }_{2}^{4} \mathrm{He}24He , balancing both the atomic and mass numbers.
