The amount of refrigerant that can be recovered from an A/C system is influenced by several key factors directly related to the system’s operational characteristics. One significant factor is the type of refrigerant used in the system; different refrigerants have varying properties that affect their recovery efficiency. Additionally, the design of the A/C system plays a crucial role; systems that are designed for easier access and recovery will allow for more refrigerant to be extracted efficiently.

Current pressure in the system is also critical. Refrigerant recovery must take into account the system's pressure, as it determines how much refrigerant is in a gaseous or liquid state, hence impacting recovery capabilities.

The age of the vehicle is generally not a direct factor affecting the amount of refrigerant that can be recovered. While older systems may have design inefficiencies or might have experienced more wear and tear, the specific mechanisms of refrigerant recovery are more consistently influenced by the refrigerant type, system design, and operational conditions rather than the vehicle's age itself. Thus, the correct answer indicates that vehicle age does not inherently limit the potential for refrigerant recovery in the same way that the other factors do.
