Answer:
D) Hey, Kate, do you want to eat lunch together?
Explanation:
A vocative comma is a form of the comma that is used in addressing a person. This punctuation mark is used to show and emphasize the addressed person(s).
A vocative comma is used before and after the addressee, to offset it. This is because, the use of the greeting "Hey" shows that the person is directly addressed, in this case, Kate. So, the name of the receiver or the person addressed is in the middle, in between the commas.
Therefore, the correct sentence is
option D) Hey, Kate, do you want to eat lunch together?
