    In the disintegration series \[_{92}^{238}\,U\xrightarrow{\alpha }\,X\,\xrightarrow{{{\beta }^{-}}}\,_{Z}^{A}\,Y\] 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 :

    \[_{92}^{238}U\,\,\xrightarrow{_{2}{{\alpha }^{4}}}\,\,_{90}^{234}\,X\,\,\,\xrightarrow{_{-1}{{e}^{0}}}\,\,_{Z\,=\,91}^{A\,=\,234}\,Y\]
