Parent State ID: 9
State Depth: 5
Action Taken: None
Action Reasoning: To achieve the goal state where block C is on block A, the current state already satisfies this condition. Therefore, no further actions are needed.
State Description: Block a is on block b, block c is on block a, and block d is on the table. Blocks c and d are clear. The hand is empty. The current state matches the goal state with block C on block A.
Action Path: ['unstack(d, c)', 'put-down(d)', 'pick-up(c)', 'stack(c, a)', 'None']
