Actually, I think that should be wrong, because of.
"some cups are not shirts" is given i.e., -ve stmt, then we should search for complementary +ve if its proved (should satisfy the given Statements) then absolutely -ve statement also be proved.
How:
"All cups are shirts" (+ve Complementary).
Both 1 & 2 follows.

All cups are books. All books are shirts.
By analyzing both sentences we can conclude that-:.
All cups are shirts. Because both are universal affirmation type sentence hence conclusion must be universal affirmation and it should not include common term (books). All cups are shirts it is not saying that all shirts are cups some shirts may be but not all. Hence some shirts are cups it right answer hence second follow.

From diagram we can see clearly that some books r cups & some shirts are books
some B = c
some S = B
so some S are C ( here conclusion 2 followa)
go for 1st con it doesn't follows
Finally option 2 is answer.
some B = c
some S = B
so some S are C ( here conclusion 2 followa)
go for 1st con it doesn't follows
Finally option 2 is answer.
