Answer is D only because in syllogism we have to consider all venn diagrams.

If both premises are particulars, then no valid conclusion can follow.
(eg. Some As are Bs
Some Bs are Cs
then it does not conclude that Some As are Cs)
(eg. Some As are Bs
Some Bs are Cs
then it does not conclude that Some As are Cs)

Even I think option (d) is incorrect because there is an or between two venn diagrams, so according to second venn diagram, some cows are elephants.

Option D is not correct answer since it is not satisfying all the venn diagrams. The conclusion must be true in all the cases.

Guys I think second diagram is based on possibility and we should consider that diagram in case of possibility conclusion.

Hello,
According to me,
1st option is correct. It follows rule of transitivity in syllogisms.
Some cows - p.
Are crows - q.
Elephants - r.
p -> q.
q -> r.
p -> r.
