Which sentence is punctuated correctly?
A.
At the age of 46, Bill Clinton was elected, president, for the first time.
B.
At the age of 46, Bill Clinton, was elected president, for the first time.
C.
At, the age of 46, Bill Clinton, was elected president for the first time.
D.
At the age of 46, Bill Clinton was elected president for the first time.
The other answers are incorrect because there are commas in the wrong spots. D is the right answer because the comma is right where it needs to be, which is right after 46, and no excess commas are inserted.
