Selected Answer: C
I would go with C. IPSec since... what everyone said along with the fact most of these answers tend to go with IPSec when it is an option.

I believe the distinction between PPTP and IPSec is that PPTP encrypts an entire packet in the GRE body while IPSec supports encrypting the payload. It looks like PPTP is "more correct" https://docstore.mik.ua/orelly/networking_2ndEd/fire/ch14_11.htm https://www.hypr.com/encapsulating-security-payload-esp/
