The correct answer is B) he was well-known for his theories and ideas.
Benjamin Franklin was chosen as ambassador to France because he was well-known for his theories and ideas.
At the beginning of the Revolutionary War, where the Continental Army was fighting the British troops to gain independence from England, the Colonies formed the Continental Congress in 1775 to gain strength and prepare a Declaration. In this time, Benjamin Franklin was sent to Paris, France, to reunite with Silas Deane and get the support from France and to sign a commerce treaty. The treaty was finally signed until 1778, and Benjamin Franklin was named minister to France, the first US ambassador abroad.
