The correct option is D (a), (b), (f), (g); (c), (h); (d), (i); (e)
We can see that images (a), (b), (f), and (g) have one circle and one diamond each.
Thus, these form a group.
Images (c) and (h) have one rectangle and one triangle each.
Thus, these form a group.
Images (d) and (i) have one triangle and one circle each.
Thus, these form a group.
Image (e) is the only image with one triangle.
Thus this does not belong in any of the other groups.
Hence, the final set of groups are: (a), (b), (f), (g); (c), (h); (d), (i); (e)
