Which consequence results when refrigerant-134a leaks inside automotive Heating, Ventilation, Air Conditioning (HVAC) systems, creating a hydrofluoric acid byproduct?

💡 Explanation

Leakage plus moisture causes refrigerant-134a hydrolysis; this chemical reaction creates hydrofluoric acid, which degrades lubricating oil and increases friction in the compressor because loss of oil viscosity promotes wear; therefore A, rather than other thermal effects.
