The question is asking which line from the poem "America singing" by Walt Whitman conveys the idea that each individual American is singing their own unique song. Option A, "Those of mechanics, each one singing his as it should be blithe and strong," suggests that each person is singing their own song, but it doesn't necessarily convey the idea of uniqueness. Option C, "The boatman singing what belongs to him," is similar in that it suggests each person is singing their own song, but it doesn't emphasize the uniqueness of each song. Option B, "Each singing what belongs to him or her and to none else," directly conveys the idea that each individual is singing their own unique song, which belongs to them and no one else. Therefore, the correct answer is B.
