What did the colonists promise to do if king george iii addressed their complaints in the olive branch petition? a) lay down their weapons b) reopen the port of boston c) the king strengthen the british army d) volunteer to fight in future british wars

The correct answer is a) lay down their weapons 

They promised that they would lay down their arms if the parliament accepted their proposal. However, it is said that the king called them rebels and declared them to have committed treason without even reading their petition. This was the final act of appeasing both sides before the war of independence fully began.
