According to me✓✓

➥only Ⅰ follows Because A not being D is possibility But some D are A .

________________________________

Why not ?

➥Option II:- All A are B but not all B are A so All B not being D is'nt possible

➥Option III :- All A not being B possibility, it is completely wrong because it is clearly given that all A are B

➥Option IV:- And there is No possibility of D not being C because some of D are A and all A are B and No B is C, but Some of D can be C so there is a possibility

Answer 2

Answer:

Please refer the attachment first then look here for second part

Now let us check conclusions one by one,

Ⅰ. All A not being D is a possibility

Ans - True,as we can see through the above Venn diagram that all A are not D but some A is D or in other way we can say some D is A.

Ⅱ. All B not being D is a possibility

Ans - False as we can already see some A is D where we also know that all A is B hence we can say some B is also D

Ⅲ. All A not being B is a possibility

Ans - False as we can clearly see all A is B

Ⅳ. All D not being C is a possibility

Ans -

If we consider

Case - 1

True from the above Venn diagram

But if we consider

Case - 2

False as some part of C is also in D

Now,if we go in prospective of

Case - 1

Option a and option b is correct

But,if we go in prospective of

Case - 2

Option a is correct
