Parent State ID: 4
State Depth: 3
Action Taken: pick-up(c)
Action Reasoning: The goal is to have block C on block A. To achieve this, first, we need to make block A clear to stack block C on it. Since block A is already clear, we can pick up block C, which is also clear and on the table.
State Description: Block a is on block b and clear. Block c is held in the hand. Block d is on the table and clear. The hand is holding block c.
