Solution

The correct option is A $C a O$
A rectified spirit is a mixture with a composition of ethanol (95%) and water (5%). Using quicklime $(C a O)$ to absorb water content and finally contacting the solution with anhydrous copper sulphate removes the leftover traces of water that leaves absolute alcohol.
