Which commodity would be regulated by subchapter D, Rules and Regulations for Tank Vessels?

A Vinyl Chloride
B Benzene
C Asphalt
D All of the above
AI Explanation

The correct answer is C) Asphalt. Subchapter D of the US Coast Guard regulations covers "Rules and Regulations for Tank Vessels" and applies to the transportation of bulk liquid cargoes, including substances like asphalt. Asphalt is a thick, sticky, and black substance derived from the residue of petroleum distillation and is commonly transported by tank vessels. The other options, vinyl chloride (A) and benzene (B), are also regulated substances, but they would fall under different subchapters of the Coast Guard regulations, such as Subchapter O for certain dangerous cargoes. Option D, "All of the above," is incorrect because asphalt is the only commodity specifically mentioned that is regulated under Subchapter D.
