Action Reasoning:
Since block 'c' is held by the hand, and the goal requires block 'c' to be on the table, the next logical step is to put it down on the table.

New State Description:
The hand is empty. Block 'c' is on the table and clear. Blocks 'a', 'b', and 'd' remain on the table and clear.

Action Chosen:
put-down(c)
