A company has a business application that provides its users with many different reports：
receivables reports， payables reports， revenue projects， and so on. The company has just purchased somenew， state-of-the-art， wireless printers， and a programmer has been assigned the task of enhancing all ofthe reports to use not only the company’s old printers， but the new wireless printers as well. When the programmer starts looking into the application， the programmer discovers that because of the design of theapplication， it is necessary to make changes to each report to support the new printers.
Which two designconcepts most likely explain this situation？ （）
A.Inheritance
B.Low cohesion
C.Tight coupling
D.High cohesion
E.Loose coupling
F.Object immutability
