Final answer:
The Royal Proclamation of 1763 was violated by settlers taking land for homesteading, as they disregarded the boundary set by the Appalachian Mountains and settled westward.
Step-by-step explanation:
The Royal Proclamation of 1763 was violated by D. Settlers taking land for homesteading. The Proclamation intended to prevent conflict with Native American tribes and to establish clear boundaries for colonization.
It specifically forbade settlement west of the Appalachian Mountains, reserving this land for Indigenous populations. Despite British efforts to enforce this proclamation, many colonists, eager for new land opportunities, disregarded the law and moved westward, thereby violating the Proclamation of 1763.
