Which of the following was a critical area of contention leading to the American Revolutionary War?

The issue of British taxation without representation was indeed a critical area of contention that directly fueled tensions leading to the American Revolutionary War. American colonists were increasingly frustrated by a series of taxes imposed by the British Parliament, such as the Stamp Act and the Townshend Acts. The core of their grievance was the belief that it was unjust to be taxed by a government in which they had no elected representatives or voice. This phrase, "no taxation without representation," became a rallying cry that encapsulated their frustrations and expressed the broader desire for self-governance and more political rights.

In this context, the imposition of taxes was not just about the financial burden but symbolized a larger struggle against what the colonists saw as tyrannical rule from London. The growing sense of unity among the colonies against these policies ultimately led to organized resistance, boycotts, and eventually the call for independence. Thus, this issue was foundational in shaping the revolutionary sentiment that culminated in the war.
