(D) First,determine the mass number $(A_{mass} = Z + n)$ for each atom:$A: Z = 90, n = 146, A_{mass} = 90 + 146 = 236$$B: Z = 92, n = 146, A_{mass} = 92 + 146 = 238$$C: Z = 90, n = 148, A_{mass} = 90 + 148 = 238$Now evaluate the statements:$(a)$ $A$ and $C$ have different $Z$ but same $n$ ($146$ vs $148$),so they are $NOT$ isotones. (Incorrect)$(b)$ $A$ and $C$ have same $Z$ $(90)$,so they are isotopes. (Correct)$(c)$ $A$ $(236)$ and $B$ $(238)$ have different mass numbers,so they are $NOT$ isobars. (Incorrect)$(d)$ $B$ $(238)$ and $C$ $(238)$ have same mass numbers,so they are isobars. (Correct)$(e)$ $B$ $(Z=92)$ and $C$ $(Z=90)$ have different $Z$,so they are $NOT$ isotopes. (Incorrect)The incorrect statements are $(a, c, e)$.
