Petroleum Engineering Question:

Pick out the wrong statement.

A. Higher specific gravity of petroleum products means higher C/H ratio.
B. Aromatics have lower specific gravity than corresponding paraffins.
C. Hydrocarbons of low specific gravity (e.g, paraffins) possess the maximum thermal energy per unit volume.
D. Hydrocarbons of high specific gravity (eg, aromatics) possess the maximum thermal energy per unit weight.
