Particulate data is available only for which type of vehicles?

• A. Gasoline vehicles
• B. All vehicles
• C. Diesel vehicles
• D. Electric vehicles

Answer: (C)

Particulate data refers to measurements of fine soot particles emitted from engine exhaust. Diesel engines tend to produce more particulate matter than gasoline engines because of how diesel combustion works, which makes PM a major focus of emissions testing for diesels. Electric vehicles don’t burn fuel at all, so they have no tailpipe particulates to report, and gasoline engines, while they do emit some particulates, are not the primary focus for this particular dataset. In this context, the data available for particulates is specific to diesel vehicles, which is why that option fits best.
