    In the disintegration series  \[_{92}^{238}U\xrightarrow[{}]{\alpha }X\xrightarrow[{}]{\text{ }\!\!\beta\!\!\text{ -}}_{\text{Z}}^{\text{A}}\text{Y}\] the values of Z and A respectively will be

    A)  92,236                                 

    B)  88,230

    C)  90, 234                                

    D)  91, 234

    Correct Answer: D

    Solution :

    \[_{92}^{238}U\xrightarrow{\alpha }_{90}^{234}X\xrightarrow{\beta }_{91}^{234}Y\] \[\therefore \]  \[Z=91,\]                              \[A=234\]
