What facilities are included in the Terminal Building at an airport?

The Terminal Building at an airport includes passenger terminal facilities and associated roadways, making this the correct choice. The terminal serves as a central hub where passengers check in for flights, pass through security, and access boarding gates. It typically houses ticket counters, baggage claim areas, lounges, retail shops, food and beverage options, and other amenities designed to enhance the passenger experience.

In addition to these facilities, the terminal is also connected to the airport's roadways, providing access for passengers, staff, and vehicles transporting luggage or supplies. This integration of passenger facilities with roadways is crucial for the efficient operation of an airport, as it facilitates the flow of people and services to and from the terminal.

The other choices, while relevant to an airport's operations, do not encompass the full scope of what the terminal building comprises. Ticketing areas alone do not represent the comprehensive facilities available for passengers. Maintenance and repair facilities are essential for the upkeep of aircraft but are usually located separately from passenger services. Cargo handling units are important for freight but pertain specifically to cargo operations rather than passenger travel, placing them outside the scope of terminal facilities.
