In Option A - INCORRECT.
Here, no clear definition as to the subject matter. The statement does not make much sense of we take a critical look at the aim of the writer who seeks a better explained definition.

In Option B - INCORRECT.
Here, the passenger vehicle is clearly defined to include all that's written in the main statement showing the possessive actions and informing distinctly that the passenger is/must be the one with the gross weight. It is appropriately instructive and emphatic to state in clear terms what the writer meant. Unfortunately it is not best of options.

In Option C - INCORRECT.
This statement seeks to separate the term variables i.e. the head word and subject in the sentence. It seeks to infer that the private passenger vehicle which is the head-word is registered to an individual who's the subject and the passenger vehicle, the object has gross weight of 8,000 pounds. This is a wrong interpretation of what the writer has said.

In Option D - INCORRECT.
Here, the individual is/should be the one with the gross weight and not the vehicle if we critically check the next of the writer's work. This is a misjudged perspective.

In Option E - CORRECT.
This statement is twisted in logic not to confuse the reader or the audience but to add sensationalism to the headline word which captures the two events appropriately and correctly.
