Microprocessor Assertion(A): Segment override prefix (SOP) is used when a default offset register is not used with its default base segment register but with a different base register. Reason(R): The offset registers IP and SP can never be associated with any other segment registers apart from their respective default segments. Both A & R are true and R is the correct explanation of A. A is false but R is true. Both A & R are true but R is not the correct explanation of A. A is true but R is false. Both A & R are true and R is the correct explanation of A. A is false but R is true. Both A & R are true but R is not the correct explanation of A. A is true but R is false.
