A

If neither conclusion I nor II follows

B

If either conclusion I or II follows

C

If only conclusion II follows

D

If both conclusions I and II follow

E

If only conclusion I follows

Show Answer

Correct Answer :

Option C

If only conclusion II follows

Solution :

The correct answer is If only conclusion II follows.

Step 1: Analyze the given statements
1. Only a few Laptops are Monitors: This indicates that some Laptops are Monitors, and some Laptops are definitely not Monitors.
2. Some Monitors are Keyboards: There is an intersection between the set of Monitors and the set of Keyboards.
3. Some Keyboards are Printers: There is an intersection between the set of Keyboards and the set of Printers.

Step 2: Evaluate Conclusion I
Conclusion I: No Monitors are Printers
From the given statements, no direct negative relationship or restriction is established between Monitors and Printers. A scenario where Monitors and Printers overlap is possible. Since Conclusion I makes a definite negative claim, it does not follow definitely. Thus, Conclusion I does not follow.

Step 3: Evaluate Conclusion II
Conclusion II: Some Laptops being Printers is a possibility
Since there is no restriction or negative relationship given between Laptops and Printers, it is possible for the set of Laptops to intersect with the set of Printers. Therefore, Conclusion II follows.

Hence, only conclusion II logically follows.
