Answer 1

Answer:

Option A, carbon

Explanation:

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.

Answer 2

Organic matters are generally carbon compounds. Therefore, the organic molecules contain carbon. The main reason of the presence of carbon in the organic molecules is the catenation property of carbon.
