Which sentence uses commas correctly? A. Sir would you show me, the way to the museum? B. Ms. O'Rourke is waiting outside, Mr. Martinez. C. Ride on over, Kelly and take these books to them. D. Wait Megan, we'll go to the library together.
The answer is B. Ms. O'Rourke is waiting outside, Mr. Martinez.
The comma should separate the name being addressed so A should have a comma after Sir, C should have one after Kelly as well, and D should have one before Megan.
