What are the two types of Passenger Service Units (PSU) equipped on the CRJ 200?

The correct answer identifies the two types of Passenger Service Units (PSU) found on the CRJ 200, which are categorized as Original and Advanced.

The Original PSU was part of the initial design of the CRJ 200 and includes essential features intended to provide comfort and service to passengers. The Advanced PSU, meanwhile, reflects updates and improvements that address passenger needs more effectively and may incorporate additional functionalities, such as enhanced lighting or innovative safety features.
