Which option will replace the question mark? 
A
B
C
D
Each hexagon in the chain carries the same set of markers, small corner triangles, a filled black triangle at one edge, and a circle split into a black and a white half, and each of these markers turns by the same fixed amount from one hexagon to the next along the chain. Applying that same fixed turn to the last complete hexagon tells us exactly where the black triangle and the split circle should sit in the missing hexagon.
Carrying the established, steady rotation forward by one more step lands the markers exactly where option B shows them.
So the correct answer is Option B.
