Answer: C. High-pressure.
- ALow-pressure.
- BMedium-pressure.
- CHigh-pressure.✓ Correct
- DVery high-pressure.
Why C is right
A Type II appliance is a high- or very high-pressure appliance, other than a small appliance or car AC. High-pressure refrigerants have a saturation pressure between 170 and 355 psia at 104°F, such as R-22, R-404A and R-410A; between 45 and 170 psia is medium-pressure, and below 45 psia low-pressure.
