Step-by-step explanation:
The question seeks to identify which city served as the primary base for British operations during most of the Revolutionary War. The correct answer to this question is B. New York. After the British evacuated Boston in March 1776, they captured New York and it became the main base of operations for the British army for the remainder of the war. New York's strategic location and its excellent harbor made it a fundamental part of British military strategy. The city was under British control from its capture in 1776 until the conclusion of the war in 1783, allowing the British to deploy troops, gather supplies, and maintain communication with their naval forces.
