Question

particulate matter released during manufacturing that does not change form in the atmosphere is considered to be primary pollutants from a stationary source primary pollutants from a mobile source secondary pollutants from a stationary source secondary pollutants from a mobile source

Explanation:

1. First, recall the definitions: Primary pollutants are emitted directly from sources and don't change form in the atmosphere. Secondary pollutants form from reactions of primary pollutants in the atmosphere.
2. Manufacturing (like factories) is a stationary source (not mobile like cars). The particulate matter here doesn't change form, so it's primary. So the correct option is the one with primary pollutants and stationary source.

Answer:

A. primary pollutants from a stationary source
