B2 Visa - Selecting VAC and appointment location

Doing a B2 visa for my parents and I created a DS 160 by selecting India,New delhi which is closer to my parent’s home in delhi. I submitted the DS 160

From confirmation of DS 160:

I paid the fee to see the slots , I am able to see chennai,mumbai and other locations slots also… Is it okay to book a slot in any other location other than what is mentioned in DS 160?

US TravelDocs:

Could you please advice. Thank you!

Yes, you can book at other locations than mentioned in DS-160.
