Solution

The correct option is A $C O_{2}, C u$
C and H are oxidized to $C O_{2}$ and $H_{2} O$ when heated with $C u O .$
$C O_{2}$ turns lime water milky and $H_{2} O$ turns anhydrous $C u S O_{4}$ to hydrated $C u S O_{4}$ which is blue in carbon.
$H + C u O △ - \to H_{2} O + C u$
$C u S O_{4} White + 5 H_{2} O \to C u S O_{4} . Blue 5 H_{2} O$
