Shape Matrix Reasoning Puzzle, Find the Missing Tile

Explanation

This solution was suggested by Reddit user xjxcxgxpx, and I found their reasoning to be one of the clearest and most convincing explanations. They started by looking at the rows from left to right. In each row, there is at least one black circle, and the black circle shifts one position to the left each time. When a tile contains two black shapes, the second black shape is either a square or a triangle. They also noticed that the same pattern appears diagonally from the top-right to the bottom-left. This diagonal pattern confirms the movement of the black circle and helps define the missing tile. In the last row, the first tile has the black circle on the left. The middle tile has the black circle on the right, together with a square. Therefore, the missing tile should have the black circle in the center and should include a triangle next to it. This leads to option F. What makes this explanation strong is that the same conclusion can be reached in more than one way: by checking the rows and also by checking the diagonal pattern. Since both approaches point to the same answer, I selected F as the final answer.
