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