R-410A is classified as an A1 refrigerant.

Explanation:
R-410A’s safety rating comes from the ASHRAE 34 classification system, which uses a letter for flammability and a number for toxicity. A1 means nonflammable and low toxicity. Since R-410A is nonflammable and has low toxicity, it is designated A1. This classification is a property of the refrigerant itself and isn’t conditional on operating conditions, so statements like “not specified” or “depends on conditions” don’t apply. The other options aren’t correct because there is a defined A1 rating for R-410A.
