    A)            Z ? 3, A ? 4                            

    B)            Z ? 1, A ? 4

    C)            Z ? 2, A ? 4                            

    D)            Z, A ? 2

    Correct Answer: A

    Solution :

               \[_{Z}^{A}X\to _{Z-2}^{A-4}Y+_{2}^{4}He\to _{Z-3}^{A-4}Z+_{1}^{0}B\]
