There are 6 shapes on a 9x9 grid. Which shape is closest to the gray 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: gray square at (0, 1)
Distance from target shape to cyan square at (0, 6): 5
Distance from target shape to pink square at (1, 2): 2
Distance from target shape to green rectangle at (0, 8): 7
Distance from target shape to orange rectangle at (3, 3): 5
Distance from target shape to red trapezoid at (8, 3): 10
Closest shape is the pink square at (1, 2) with distance 2</think>
