Explanation:

HAPs (Hazardous Air Pollutants) are reduced by minimizing overspray, using low-emission products, or efficient application methods. Reducing gun air pressure, UV-curing products, and roll-on products all lower HAP release. Over-reducing the primer thins it, increasing overspray and HAP emissions, so it does not reduce HAPs.

Answer:

A) over reducing the primer.
