There are 5 shapes on a 4x4 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 (2, 3)
Distance from target shape to blue trapezoid at (2, 0): 3
Distance from target shape to red rectangle at (1, 0): 4
Distance from target shape to orange rectangle at (3, 0): 4
Distance from target shape to gray square at (0, 0): 5
Closest shape is the blue trapezoid at (2, 0) with distance 3</think>
