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 >>>.

Conclusion: Some cat is not door, is correct?

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

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.

The above first statement is not clear then how can we decide the answer? There may be a chance to be some cats can be doors and can't be, will you please tell me the proper solution for this?

The statement clearly says that no door is dog but it didn't specify that no cat is door. So here door can be cat or cat can be door. So only 3 follows.

Only conclusion (3) follow because,
According to 1 Venn diagram its follow the conclusion. But in 2 Venn diagram it does't. That's why answer is wrong.
Same its with conclusion (2) and conclusion (2) is also wrong.

Option 1 and 2 are negatives, and it is true, if negative conclusions are true take its negation. If negation is true then negative statements will not follows, otherwise it follows.
