Parent State ID: 0
State Depth: 1
Action Taken: pick-up(d)
Action Reasoning: To achieve the goal state where block C is on block A, we need to move block D out of the way first. The first action is to pick up block D since it is clear and the hand is empty.
State Description: The hand is holding block D. Block A is still on block B and clear. Block C is on the table and clear. Block B is on the table, and Block D is no longer on block C and clear. The hand is no longer empty.
Action Path: ['pick-up(d)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: The precondition that block D must be on the table is not satisfied.
