Yes, I am sure. Benjamin Franklin did indeed make a notable plea for the delegates to accept the U.S. Constitution during the Constitutional Convention. His speech near the end of the convention highlighted the necessity of unity and urged the members to support the document despite their differences. Franklin was not the mastermind behind key compromises or a primary author of the Constitution, but his advocacy for its acceptance was influential. Thus, the correct answer remains C) He made a plea to delegates to accept the U.S. Constitution.
