Answer: Option (b) is the correct answer.
Explanation:
Compounds which have carbon and hydrogen atoms in their structure or formula are known as organic compounds.
For example, a molecule of [tex]CH_{4}[/tex] is organic because it has carbon and hydrogen atom in its formula.
Whereas atoms which do not contain carbon atom in their formula or structure are known as inorganic molecule. For example, NaCl is an inorganic molecule.
Thus, we can conclude that an organic molecule will always contain carbon and hydrogen.
