Ordinary Dry Chemical Extinguishing Agent is associated with which classes?

Explanation:
The main idea is which fire classes this powder is effective against. Ordinary dry chemical works by coating the fuel surface and interrupting the chemical reactions occurring in the flame. That coating and heat absorption make it effective on fires involving ordinary combustibles (Class A) and flammable liquids (Class B). It’s not typically relied upon for energized electrical fires (Class C) because the residue can interfere with equipment and other agent types are preferred there. So, the best match is fires involving Class A and Class B.
