What was the British response to the defiance of colonists against the Proclamation of 1763?

The British response to the defiance of colonists against the Proclamation of 1763 involved sending additional troops to the colonies. The Proclamation was intended to stabilize relations with Native Americans by restricting colonial expansion west of the Appalachian Mountains, but colonists largely ignored it and continued to move into these areas. In response to this defiance and the growing tensions, the British government felt it necessary to deploy more regular troops to maintain order and ensure enforcement of the Proclamation. This military presence aimed to prevent conflicts between settlers and Indigenous peoples, thereby attempting to uphold British authority in the colonies.

The other options, while they reflect various British policies during this period, do not accurately describe the direct response to the specific defiance of the Proclamation. For instance, although taxation would later be ramped up as tensions rose, it was not the immediate reaction to the Proclamation. Similarly, revoking colonial charters occurred later in the context of growing rebellion, and encouraging westward expansion directly contradicts the intent of the Proclamation itself. Thus, sending additional troops aligns most closely with the British strategy to manage colonial defiance immediately following the Proclamation's issuance.
