The correct answer is: D. wouldn’t go
The sentence is about the speaker’s intention not to go to a place again because of the rude behavior of the people there. The verb “wouldn’t go” expresses this intention clearly and concisely.
The other options are not as appropriate. “Won’t go” is also about the speaker’s intention not to go to a place again, but it does not specify the reason for this intention. “Hadn’t gone” is about the speaker’s past experience of not going to a place, but it does not express their intention not to go there again in the future. “Didn’t go” is about the speaker’s past action of not going to a place, but it does not express their intention not to go there again in the future.
In conclusion, the correct answer is “wouldn’t go” because it is the only option that expresses the speaker’s intention not to go to a place again because of the rude behavior of the people there.
