There are 6 shapes on a 4x4 grid. Which shape is closest to the cyan 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: cyan square at (2, 3)
Distance from target shape to brown square at (0, 0): 5
Distance from target shape to orange rectangle at (0, 1): 4
Distance from target shape to gray square at (2, 2): 1
Distance from target shape to pink square at (3, 3): 1
Distance from target shape to purple rectangle at (1, 0): 4
Closest shape is the gray square at (2, 2) with distance 1</think>
