There are 3 shapes on a 5x5 grid. Which shape is closest to the pink 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: pink square at (4, 4)
Distance from target shape to green trapezoid at (0, 0): 8
Distance from target shape to red trapezoid at (2, 3): 3
Closest shape is the red trapezoid at (2, 3) with distance 3</think>
