Usually, criminals are guilty and some of the guilty people are criminals so there is a relation with crime and guilt.

I feel option D is the correct one, please explain the reason that the answer is C.

I think Option A is more appropriate in this case. If we go for a venn diagram in this case then it becomes evident.
Prachi said:   1 decade ago
I don't agree with the answer. Here the given statements are to be considered absolute, and hence as mentioned in the statements only option A holds true.

Please explain further why option C is true?

I don't agree with the answer. Middle term distributed twice. Only conclusions are Some guilty are terrorists and Some criminals are terrorists. How is the answer "Some guilty are criminals".
