well we all understand that hf and vhf are line of sight.
please correct me if im wrong.
Since you ask, you are wrong.

HF is not line of sight. HF does have a ground wave component which can be considered line of sight, but the function of HF is medium to longer range (2-3 thousand miles typically) and for that it uses the skip wave. In certain ionospheric conditions HF comms can extend to very long range.

So...

The question is crap, and meant VHF. The answer is B.

Are we done?
