A) Heptane is $8 \mathrm{~kJ} / \mathrm{mol}$ more stable then 3,3-dimethylpentane.
B) 3,3-Dimethylpentane is $8 \mathrm{~kJ} / \mathrm{mol}$ more stable than heptane.
C) Stabilities cannot be compared since they are not isomers.
D) Stabilities cannot be compared since they give different combustion products.
