In modern air conditioning systems, the commonly used refrigerant is b) Freon-12. However, older systems might use other refrigerants like R-22 (HCFC). Newer systems often use more environmentally friendly options like R-134a (HFC) or R-410A.
Explanation:
Freon-12 (CFC-12): While historically widely used, its production and use have been phased out due to its ozone-depleting properties.

R-410A (HFC): Another commonly used modern refrigerant with improved environmental characteristics.
