Correct answer: B
Correct answer: Para-virtualization
Para-virtualization: the guest OS is aware of virtualization and is modified to use hypercalls for privileged operations.
Full virtualization: hardware is emulated so an unmodified guest OS can run.
So the technique that requires guest OS modification is para-virtualization.
