Answer:
The correct answer is option C.
Explanation:
Metallic sulfides on combustion gives metallic oxides along with sulfur dioxide as product.During combustion reaction oxygen reacts with compound.
[tex]M_2S_x+(\frac{3x}{2})O_2\rightarrow M_2O_x+xSO_2[/tex]
So, when compound of containing metal and sulfur undergone combustion reaction it gives compound X and compound Y.
Compound X contains metal atom which means it is metal oxide.
Compound Y contains sulfur atom which means it is sulfur oxide.
