Answer: Option (c) is the correct answer.
Explanation:
Carbon is a non-metal and it belongs to group 14 of the periodic table.
Atomic number of carbon is 6 and its electronic distribution is 2, 4. And, in order to attain stability a carbon atom can either lose its valence electron or it can gain 4 electrons from another atom by sharing or donating.
Hence, a carbon atom is able to form a single, double or a triple bond with its own or another atom. This makes carbon atom to form multiple bonds.
Thus, we can conclude that carbon bond to many elements simultaneously because it is capable of forming multiple covalent bonds.
