Final answer:
Thomas Paine in "Common Sense" advocates for the American people to independently address their grievances rather than relying on British concessions, aligning with the need for American independence.
Step-by-step explanation:
Thomas Paine's logic in sentence 5 of "Common Sense," which suggests, "As we have, without any good effect therefrom, withheld our trade to obtain a redress of our grievances, let us now try the alternative, by independently redressing them ourselves," aligns with option (C): Instead of relying on Britain, the American people should fix their own problems and accept the offer to resume trading. Paine argues for a proactive approach where Americans take control of their own destiny, addressing grievances independently rather than waiting for Britain to make concessions. This sentiment underscores a shift towards self-reliance and bolsters the case for American independence.
