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, 0)
Distance from target shape to purple square at (2, 2): 2
Distance from target shape to gray trapezoid at (3, 2): 3
Distance from target shape to orange right_triangle at (1, 3): 4
Distance from target shape to pink square at (0, 3): 5
Distance from target shape to brown right_triangle at (0, 0): 2
Closest shape is the purple square at (2, 2) with distance 2</think>
