To solve this question, the user needs to know about COBOL programming in the context of IMS message processing programs (MPPs).
The statement is true. IMS message processing programs (MPPs) do not use non-IMS input or output statements such as READ, WRITE, REWRITE, OPEN, and CLOSE. Instead, they use IMS-specific input and output statements such as GU, GN, GV, and GN.
Option A is correct.
Option B is incorrect because the statement is true, so option A is the correct answer.
