Answer:

Option A, carbon

An organic molecule consists of carbon as a elementary atom. Thus, all molecules in which a carbon atom bonds to other atoms such as oxygen, hydrogen, nitrogen, another carbon atom  etc. are considered as organic molecule.

For example -

Methane - CH_4 Here, carbon atom is bonded to four hydrogen atoms

Methanol - CH_3OH\\ Here, carbon is attached to three hydrogen atoms and one hydroxyl (OH) ion.

Hence, option A is correct.
