B: They had strained relationships with both American Indians and colonists.
This statement is true about the British relationships after the war.
<u>Explanation</u>:
The "French - Indian War" largely affected the relationship between 'Britain' and the colonies. Britain became very "active" in colonial political and economic affairs. They had huge war debt and so they imposed heavy taxes on the colonies and American Indians unfairly. This caused their resentment towards British.
Britain stopped relaxing their strict regulations and increased their authority over colonial politics. Colonists were very upset as there was taxation without representation and they did not have any say in the government.
