In A the big shape sits in the middle; in B it has changed size and position. Which answer figure is related to C in the same way?

The big central shape shrinks to half its size and moves into the bottom-right corner, while the small mark in the top-left corner stays put. So the orange triangle becomes a half-size triangle, still pointing up, in the bottom-right corner, and the star stays top-left: (d). (a) also moves the star, (b) uses the wrong corner and (c) turns the triangle over.
