Name one common type of air conditioning system.

A central air conditioning system is a common type of air conditioning system that provides cooling throughout an entire building or home. This type utilizes a network of ducts to distribute conditioned air, ensuring that all rooms receive a consistent and comfortable temperature. Central air conditioning is known for its efficiency in cooling larger spaces and often includes additional features such as air filtration and humidity control. It allows for ease of temperature regulation with a centralized thermostat, making it a popular choice for residential and commercial environments alike.

The other options represent different configurations and capacities of air conditioning systems but are generally used for more localized cooling solutions rather than providing comprehensive climate control across a larger area.
