A, B and C would all be equally good, depending on what the speaker or writer intends to say. C is not as good, but it could work also.

I see no problem with D, either.

Hi, Jamie.

Are you saying that "utterly lost" does not sound right ?
(
My Goodle research produced these results:
They were thoroughly lost 105
They were completely lost 3,780
They were truly lost 444
They were utterly lost 790

)

Alex, I simply forgot to mention that D is also good.

It's C that I found a bit iffy.

I feel sorry for these Vietnamese students having to do these messed-up exercises, where you're supposed to choose the correct answer and all the answers are correct.
