Final answer:
Thomas Paine argues that America does not need to depend on Britain for its future happiness and prosperity.
Therefore, the correct answer is: option C) He refutes the idea that America depends on Britain, using the opinion that America's trade has a secure future.
Step-by-step explanation:
Thomas Paine's argument in the excerpt from Common Sense refutes the notion that America's prosperity is inherently linked to its relationship with Great Britain.
Instead, Paine suggests that America would have flourished much more without any European interference, emphasizing the country's ability to trade necessities of life which will always find a market in Europe.
His underlying point is that just because something was beneficial in the past does not mean it will remain so, just as a child moves from milk to more substantial food as they grow.
Therefore, the correct answer to the question is: He refutes the idea that America depends on Britain, using the opinion that America's trade has a secure future.
