Out of two statements, if one is negative, the conclusion must be negative.

So only 1 and 2 options may be right.
But 1 and 2 are wrong.
Hence there is no answer.

1 2 3 all are right.
IGHT KARL said:   8 years ago
The answer should be 1, 2 and 3.

The result is 1 2 3, then how it come option 3 only?

If negative conclsion is correct then we have to draw alternative diagram (that is shown in discuss some doors are cats) now check all statements if steatements are follow that diagram is consider now check again all conclusions.

Now conclusion I and II does not follow only conclsion III follows.

Why option B is not correct?
Aathi said:   7 years ago
Yes, I agree the only option 3 is correct.
Deepanshu Samdani said:   7 years ago
The answer should be in "some-not" because universal affirmative and universal negative gives the result in the particular negative when the premises is only distributed in the universal negative. So, the correct answer should be the "some cats are not the door".
