The correct answer is A. The colonists wanted to be free from Great Britain.
Step-by-step explanation
Before being an independent country the United States was a British colony, for this reason, the British rulers had dominion over all the American territory, its natural resources, and its control. This caused abuses of power to arise towards Native Americans and settlers. This caused discontent in the population which promoted the idea of independence because they considered that they could govern the country by their means. This caused a war in which they defeated the British and won their independence. After its independence, it became necessary to establish new laws on all matters, to avoid the accumulation of power in one person or group, justice for all people, a new democratic government system, among others. Therefore, it was necessary to establish a new constitution. So the correct answer is A. The colonists wanted to be free from Great Britain.
