(A) Transuranic elements are those with atomic numbers greater than $92$. In uranium ores like $U_3O_8$,trace amounts of $Neptunium$ ($Np$,$Z=93$) and $Plutonium$ ($Pu$,$Z=94$) are found due to the neutron capture by $U^{238}$ followed by $\beta$-decay processes. Therefore,the correct pair is $Np$ and $Pu$.
