Sam has to apply a patch on his Oracle Applications system. He has already brought down the services on the application tier. The database tier and the database listener are up and running. He goes through the readme of the patch and discovers that three prerequisite patches need to be applied on the system before applying the main patch. Now, Sam needs to check if these prerequisite patches have already been applied to the system, so he decides to extract this information from the database. Identify the tables that would help him in extracting the above information from the database. (Choose all that apply.)
