Question

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

Explanation:

The Olive Branch Petition was a final attempt by the colonists to reconcile with Britain. If King George III addressed their complaints, the colonists promised to lay down their weapons as they sought peaceful resolution. Reopening the port of Boston was a British action related to the Intolerable Acts, not a colonist promise. Helping strengthen the British army or volunteering to fight in British wars were not part of the petition's promise.

Answer:

A. lay down their weapons
