Final answer:
Option (D), Colonists declared independence from Britain due to increasing economic burdens from taxation without representation, restrictive laws, and the British military presence, culminating in armed conflict at Lexington and Concord.
Step-by-step explanation:
The colonists declared their independence from Britain due to a series of events and growing tensions that began with the end of the French and Indian War. In the aftermath, Britain sought to tax the colonists to pay for the war debts and utilized troops to enforce new laws. Events such as the imposition of the Stamp Act and Townshend Acts, which levied taxes without colonial representation, sparked outrage and cries of 'no taxation without representation'.
The introduction of the Coercive Acts, punishing Massachusetts for the Boston Tea Party, further inflamed relations. With British troops enforcing unpopular policies and the colonial desire for self-governance growing, clashes became inevitable. After confrontations at Lexington and Concord, the Second Continental Congress declared independence, marking the formal break and the beginning of the American Revolutionary War.
