Question

7. Which sentence does not contain any errors in period usage?

A Rev Jesse L. Jackson has run for public office
B. Have you read The Hobbit by J. R. R. Tolkien?
C. Sgt Eva Miller will be able to answer your question.
O D. My brothers platoon leader is Lt Brian Lee

Answer 1

It is the 2nd one because in number 1 Rev. should have a period after it.
in the 3rd one Sgt. should have a period after it.
In the 4th one Lt. should have a period after it.
A period in this case abbreviates a title given to someone
