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