Kindly tell the correct option asap

Dear Student,

Isotopes are those chemical elements having same atomic no. But different atomic mass no. And Isobars is the reverse of this .
So , among the above options , the option D is the correct set of isobars and isotopes. 
As, U,Y,Z have same atomic mass no. But different atomic no. So they are isobars.
        And in X,V,Q, & T,W,Y  all the elements in thes two pairs have different atomic mass no. But same atomic no. So these both pairs are isotopes.
