Identify the incorrect statement from the following:

Explanation

Option A is true because a higher specific gravity in petroleum products indicates a higher carbon to hydrogen ratio. Option B is false since aromatics actually have a higher specific gravity than their corresponding paraffins. Option C is correct as low specific gravity hydrocarbons, like paraffins, possess maximum thermal energy per unit volume. Option D is also true because hydrocarbons with higher specific gravity, such as aromatics, contain more thermal energy per unit weight.
