We cannot say the options 1 and 2 because the relationship between the doors and the cats is not given in the statements.
Swati said:   9 years ago
According to syllogism rule: If on premises is -ve. Conclusion must be -ve.

So the conclusion 1 and 2 will be followed.
Srima said:   9 years ago
Answer should be Conclusion 1, 2 & 3 follows. Since they have not mentioned the relation between the door and the cat.

According to me 1, 2 are correct, the 3 one doesn't stand as the dogs are cats but not a dog. Its not viceversa.
Ratnapriya kumari said:   9 years ago
Answer should be 1, 2, 3 because there is no relationship between door and cat.

I agree with you @Monika.
Maira said:   1 decade ago
But no. 4 is not valid as the conclusion says all cats are dogs but right conclusion is all dogs are cat.
