E Correct answer
Explanation

This option is correct because dihedral angle between the H-atom is staggered conformation of ethane is 60˚, nitroethane shows tautomerism due to presence of α-hydrogens and functional isomerism with ethylnitrite and because of angle stain, the heat of combustion of cyclopropane is higher than that of propane.
