The input contains 3 blocks in 2 stacks. From left to right:
- Stack 1 has 1 level. Level 1 has a orange block.
- Stack 2 has 2 level. From bottom to top: level 1 has an green block, level 2 has an blue block,
As such, for the question "What is the spatial relation betweeen the green block and the blue block?",since the green block is directly below the blue block and they are in the same stack, the correct answer is "<Output> B".
<Output> B
