I think only 1 follows because all buildings are chalks but it is not clear that all chalks are building, the building is inside chalk.

I think option D is correct because conclusion may be correct may not be correct but we can't say it's definitely true. So we can't say any conclusion is true. Think in this way and help me out.

Option A is correct because in diagram we can see cleary there is no any relation between building and toffee.
So, no building is tofee is follows.
So, no building is tofee is follows.

Is there any relation (see the diagram) between toffee and buildings? No, not at all. So, conclusion: 1 is true. Now, given that, all buildings are chalks, not all chalks are buildings. So, conlusion: 2 is wrong. Therefore, Option A is right.

Option E is correct. If all A are B, then all B is A. Or simply apply symmetry property i.e. if A = B then B = A.

I think answer D will be correct one is n't it. Because some chalks will be building.

But I think some chalk will be building so I think answer D is correct.

Option E is correct. All buildings are chalks is a statement. No building is a toffee. It has been clearly explained in the Venn diagram.

If all buildings are chalks then the reverse condition is also possible, I mean all chalks can be buildings.
