There are 5 shapes on a 5x5 grid. Which shape is closest to the orange square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: orange square at (4, 4)
Distance from target shape to brown right_triangle at (3, 0): 5
Distance from target shape to yellow rectangle at (2, 4): 2
Distance from target shape to pink rectangle at (2, 2): 4
Distance from target shape to red right_triangle at (0, 2): 6
Closest shape is the yellow rectangle at (2, 4) with distance 2</think>
