AI Explanation
The correct answer is A) activated alumina or silica gel desiccant beads. Standard filter/driers used in many commercial refrigeration units typically contain activated alumina or silica gel desiccant beads. These desiccant materials are effective at absorbing and removing moisture from the refrigerant system, preventing the buildup of ice or condensation that could damage the equipment. The other options, activated charcoal and alcohol-based liquid drying agents, are not commonly used in standard commercial refrigeration filter/driers.
