    In the disintegration process \[A\xrightarrow{\alpha }B\xrightarrow{-\beta }C\xrightarrow{-\beta }D\] The correct statement is

    A)  A and C are isotones

    B)  A and B are isobars

    C)  A and D are isotopes

    D)  A and B are isotopes

    Correct Answer: C

    Solution :

    \[_{y}^{x}A\xrightarrow{\alpha }_{x-2}^{x-4}B\xrightarrow{-\beta }_{y-1}^{x-4}C\xrightarrow{-\beta }_{y}^{x-4}D\] Hence A and D are isotopes here. Hence, the correct option is [c].
