Final answer:
The incorrect pairing is b) Proclamation of 1763/Appalachian Mountains boundary.
Step-by-step explanation:
The correct answer is b) Proclamation of 1763/Appalachian Mountains boundary.
The Proclamation of 1763 was issued by the British government after the Seven Years' War and it aimed to prevent further conflicts between Native American tribes and British colonists. It established a boundary line along the Appalachian Mountains, prohibiting colonists from settling west of the line.
However, the Appalachian Mountains were not the actual boundary specified in the proclamation. The correct boundary specified in the Proclamation of 1763 was along the crest of the Appalachian Mountains.
Therefore, the pairing of 'Proclamation of 1763/Appalachian Mountains boundary' is incorrect.
