Which sentence is punctuated correctly? A. My friend, Greg, likes to bake cookies for the people in the office. B. My friend, Greg likes to bake cookies for the people in the office. C. My friend Greg likes to bake cookies for the people in the office. D. My friend Greg, likes to bake cookies for the people in the office.

The correct answer is letter A. My friend, Greg, likes to bake cookies for the people in the office.

Explanation:

What we have in this sentence is an appositive, a word or phrase immediately following and renaming another word or phase. Our appositive here is "Greg", which is renaming the noun "friend". Since "Greg" is only giving additional but not essential information, it could easily be removed from the sentence. Notice how the sentence would still make sense: " My friend likes to bake cookies for the people in the office." Since this appositive is not a restrictive one, it should be framed by commas. That is why the best option is letter A.
