Correct Answer: Option A
Explanation

When calcium oxide (CaO) reacts with carbon (C), it produces calcium carbide (CaC\(_2\))and carbon monoxide (CO). This reaction occurs at very high temperatures, around 700°C. 

                  CaO   +  3C  →  CaC\(_2\)  +   CO

There is an explanation video available below.
