you went to antarctica this summer didnt you?
choose 1 answer:
a you went to antarctica this summer didnt you?
b you went to antarctica this summer, didnt you?
c you went, to antarctica, this summer didnt you?

Explanation:

This is a tag question in English. For a positive main clause followed by a negative tag question, no comma is needed between the main clause and the tag. When an adverbial phrase ("this summer") is placed at the end of the main clause, the tag question directly follows it without an extra comma. Option B correctly places the comma only before the tag question after the main clause and its adverbial.

Answer:

B. You went to Antarctica this summer, didn't you?
