- DNone of above

Answer
Correct option: A.
Difference in size
Ethane have a higher boiling point than methane because molecules of ethane $(\left(\mathrm{C}_2 \mathrm{H}_6\right))$ have more Van der Waals forces $($intermolecular forces$)$ with neighboring molecules than methane $(\mathrm{CH}_4)$ due to the greater number of atoms present in the molecule of ethane compared to methane.
