C. vanadium pentoxide
D. nickel

Pick out the wrong statement.

A. Aromatics have higher specific gravity than paraffins,
B. Gross calorific value (GCV) of petrofuels is equal to (12400 - 2100 ρ2) where, ρ is the specific gravity of the fuel at 15.5°C.
C. Heavier petrofuels have higher GCV on weight basis (i.e., Kcal/kg) but lower GCV on volume basis (i.e., Kcal/litre).
D. Higher specific gravity of petrofuels means higher C/H ratio.
