    D Only a few Manuals are Printers. All Manuals are Scanners. All Menus are Printers. Correct Answer Incorrect Answer
    E Both option (b) and option (d) are correct Correct Answer Incorrect Answer

    Solution

    From Statement I. Some Menus are Scanners (I) + All Scanners are Manuals (A) → Some Menus are Manuals (I) → Probable conclusion → All Manuals can be Menus (A). Hence conclusion I follows. No Printer is a Menu (E) + Some Menus are Scanners (I) → Some Scanners are not Printers (O*). Hence conclusion II does not follow. From Statement II. All Menus are Manuals (A) → Probable conclusion → All Manuals can be Menus (A). Hence conclusion I follows. All Scanners are Printers(A) → Conversion → Some Printers are Scanners (I). Hence conclusion II follows. From Statement III. Only a few Manuals are Scanners (I) + Only a few scanners are Menus (I) → Probable conclusion → All Manuals can be Menus (A). Hence conclusion I follows. Only a few scanners are Menus (I) + A few Menus are Printers (I) → No conclusion. Hence conclusion II does not follow. From Statement IV. Only a few Manuals are Printers + [All Menus are Printers (A) → Conversion] → Some Printers are Menus (I) → Probable conclusion → All Manuals can be Menus (A). Hence conclusion I follows.   Only a few Manuals are Printers (I) + [All Manuals are Scanners (A) → Conversion] → Some Scanners are Manuals (I) → No conclusion. Hence conclusion II does not follow.
