List the two types of Passenger Service Units (PSU) equipped on the CRJ 200.

Explanation:
CRJ 200 PSUs exist in two configurations that you could encounter on the aircraft: Original and Advanced. The Original unit was the first-generation PSU installed on the early CRJ 200s, while the Advanced version was introduced later as an upgrade with revised electronics and mounting provisions. Recognizing that both variants are possible on the fleet is important for maintenance and service, because each version has its own specific parts, wiring, and procedures. The option that combines Original and Advanced correctly reflects the two PSU types used on the CRJ 200. The Modular design is a different PSU approach used on other aircraft, not the two variants typically found on this model.
