There are 3 shapes on a 4x4 grid. Which shape is closest to the yellow trapezoid in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: yellow trapezoid at (0, 0)
Distance from target shape to pink right_triangle at (2, 0): 2
Distance from target shape to gray trapezoid at (1, 3): 4
Closest shape is the pink right_triangle at (2, 0) with distance 2</think>
