Which is the highest fireproof rating for shingles?

Explanation:
Class A is the highest fire resistance rating for shingles. Roofing materials are classified as Class A, B, or C, with Class A offering the greatest resistance to fire—greatest resistance to ignition and slower flame spread in standard fire tests. Because of that stronger performance, Class A shingles are the top-rated option, which is why the correct choice is the one that reflects that rating. Lower classes (B or C) indicate progressively less fire resistance.
