Carbon.
Reason: This can be explained by a simple principle known as octet rule. Carbon has 6 electrons. The first shell is filled with 2 and the second with 4. Since the octet configuration for second shell is half satisfied, the atom is rendered stable.
The other given atoms have unsatisfied octet configurations and hence either lose or gain an electron to form their corresponding ions in order to attain a stable octet configuration.

An ion? Carbon, with it's +4 valence is less likely to form an ion than +1 Sodium, or -1 Chlorine, or -2 Oxygen.

Carbon. You have to heat calcium oxide and carbon to thousands of degrees to make calcium carbide, CaC2. Even so, CaC2 is an acetylide rather than a true carbide. The only true carbides are Al4C3 and Be2C.
