In A the orange arrow and the blue arrow each turn on the spot to give B, but not in the same way. Which answer figure is made from C by the same rule?

The orange arrow turns a quarter turn clockwise (up to right) while the blue arrow turns a quarter turn anticlockwise (left to down). So in C each orange shape turns clockwise and each blue shape anticlockwise: the orange arrow from up-right to down-right, the blue pointer from down to right, the orange pointer from left to up: (d). (a) turns everything clockwise, (b) everything anticlockwise and (c) turns each colour the wrong way.
