Final answer:
The best supporting quote for "Give me liberty or give me death!" is "I know not what course others may take..." as it expresses personal commitment to liberty.
Step-by-step explanation:
The quote that best supports Patrick Henry's famous statement "Give me liberty or give me death!" from his speech advocating for independence from British rule is "I know not what course others may take...". This quote captures the essence of Henry's determination and commitment to liberty, even at the cost of his life.
The other quotes listed refer to principles found in the Declaration of Independence, which focus on inherent rights and governmental responsibilities, but do not directly echo the personal resolve expressed in Henry's impassioned declaration for liberty or death.
