The nature of oxides V₂O₃ and CrO is indexed as ‘X’ and ‘Y’ type respectively. The correct set of X and Y is:

Given data : It is given to identify  the nature of oxides V₂O₃ and CrO is indexed as ‘X’ and ‘Y’ type respectively. The correct set of X and Y is, from the given option.

Explanation :

In V₂O₃ the V is +3 oxidation state
and in case of CrO is +2 oxidation state in this oxidation is basic. 

Hence , the correct option ( A).$X=basic ; Y= basic$
