Yes agree to all guys as there is no other possibility except the door but as in all venn diagram problems we leave the possibility scenario here also drop 3 will be correct.

But no. 4 is not valid as the conclusion says all cats are dogs but right conclusion is all dogs are cat.

Conclusion: Some cat is not door, is correct?

By tick and cross method.
1. Universal negative so both are distributed.
2. Universal positive so dogs distributed and cats not distributed.
Then removing the common term we get option 1 as correct.
Further 3 conclusion as a statement is true.
But no cat is door i.e. option 2 is not correct since the rule suggest cat is not distributed in the premises hence it can't be distributed in the conclusion.
So final answer is option B.
<<< peace >>>.

Well there is a lot of discussion over this question so I want to put my opinion.
First of all No+All = Some.
Now Let's c d conclusions:
Conclusion I is correct in general i.e No door is cat.
Conclusion II is also correct as it is converse of Conclusion I.
Conclusion III is obvious because No+All = Some.
And lastly conclusion IV which is just the converse of Conclusion III. So I think there is no proper option to the question.

Yes: Only (3) because, no relation is given between cats and door; if option (1) is given no door is dog it follows.

Answer should be Conclusion 1, 2 & 3 follows. Since they have not mentioned the relation between the door and the cat.

Yes, The answer should be 1,2 & 3 follows as the dog is the subset of cat and the cat is nowhere related to the door.
