A carbon atom has a strong tendency to do which of the following:

A. Double bond with electrons

B. Receive electrons

C. Donate electrons

D. Share electrons

The answer c is right because if we study ionic bond and covalent bond

Those elements which are highly electronegative and highly electropositive they form ionic bond.

And those elements which are less electronegative and have same charges on a atom they foam covalent bond Ex: Hcl, co2
