Here, there are two sets of three figures each.
The pattern followed between second and third figure of first set will be replicated  by second and third figures of second set.
The blackened triangle at the top changes to the opposite side.
The right sided surface comes to the front side.
In the figure (5) of the option this pattern is followed.
Also, the side figure should be a pattern of circular figurines as evident from the rotation of figures in first second and third figures.
Therfore, option E is correct.
