By rule we can say that option 4 is correct but why this either (2) or (3).

By the rule that has been followed inthe previous sections, only option 1 and 4 is correct. Then why its coming to 2 or 3 as we have to conclude from all possible venn diagrams. So only option 1 and 4 is correct.

Latest and easiest method to solve any syllogism problems is Raval's notation.Just note down statements in Raval's notation and deduce the conclusions at a simple glance.Here statements are K - S, S - St, StSt - P conclusion 1 P - St is correct by reverse reading of StSt - P,conclusion 2 and conclusion 3 forms a complimentary pair so either of them must be true, conclusion 4 S - K is simply reverse of statement K - S

Only Conclusion 1 & 4 Follows but either 2 or 3 is incorrect.

As per the rule I can derive only two conclusion.

Some staplers are pens and some keys are staplers.

So conclusion we can conclude that 1. Some pens or staplers and 4. Some staplers are keys.
