Overfilling a refrigerant container is extremely dangerous because of the high pressures generated. The generation of pressure is the result of what?

Correct Answer: Option C — hydrostatic pressure of the expanding liquid

Refrigerants are incompressible liquids. Overfilling a container leaves no vapor cushion; as ambient temperatures rise, liquid expansion exerts immense hydrostatic pressure, exponentially exceeding the burst pressure of the cylinder and causing catastrophic failure.
