I would be happy to select 127.0.0.1, but there is no such an answer. The closest one is 120.0.0.1. I guess the test organizers did a type error here and really meant 127.

Badly written question with a clear typo in the answer:
The name localhost normally resolves to the IPv4 loopback address 127.0.0.1, and to the IPv6 loopback address ::1.
The closest possible answers is either B or C…..go figure
