There are 6 shapes on a 4x4 grid. Which shape is closest to the cyan 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: cyan rectangle at (2, 2)
Distance from target shape to red square at (1, 1): 2
Distance from target shape to pink square at (3, 2): 1
Distance from target shape to purple rectangle at (3, 3): 2
Distance from target shape to gray square at (3, 0): 3
Distance from target shape to orange rectangle at (0, 3): 3
Closest shape is the pink square at (3, 2) with distance 1</think>
