Parent State ID: 0
State Depth: 1
Action Taken: unstack(b, c)
Action Reasoning: To achieve the goal state where Block C is on Block B, we first need to clear Block C by unstacking Block B from it. This will allow us to later stack Block C on Block B.
State Description: Block c is clear and on the table. Block b is held in the hand and is no longer on Block c. Block a is on the table and is clear. Block d is on the table and is clear. The hand is holding Block b.
Action Path: ['unstack(b, c)']
