Solution

The correct option is B
Cuprous and cupric

When an element forms two monoatomic cations (representing different oxidation states), the two ions are distinguished by using the ending 'ous' and 'ic'. The suffix 'ous' is used for the cation with lower oxidation state while the suffix 'ic' is used for the cation with higher oxidation state.

For example:
$C u^{+}$ (oxidation number +1) cuprous
$C u^{2 +}$ (oxidation number +2) cupric

$C u C l$ is called Cuprous Chloride
$C u C l_{2}$ is called Cupric Chloride

Q. Most transition metals form multiple cations, that is, they have more than one possible amount of positive charge. Virtually all of the transition metals form dipositive

The principal exceptions to this predominance of cations with a
