Crankcase emissions are categorized under which type of emissions?

Explanation:
Crankcase emissions come from blow-by gas and engine oil vapors, which form tiny oil droplets that are carried away as a mist. That oil mist is particulate matter, not a gaseous pollutant produced by combustion. So these emissions are classified as particulates rather than NOx, volatile organic compounds, or carbon monoxide.
