Blinded by the sun's reflection, the crevasse was all but invisible until the climbers nearly stumbled into it.
(A) Blinded by the sun's reflection, the crevasse was all but invisible until the climbers nearly stumbled into it.
It
WASN'T the crevasse that got blinded by the sun's reflection, so OUT!!
(B) The climbers, blinded by the sun's reflection, nearly stumbled into the crevasse, which they had found until then all but invisible.
The gramatical structure is fine, but this doesn't make much sense, coz
finding something invisible is not part of the issue here, but let's just hold this and see if there's any better choice.
(C) The crevasse was all but invisible to the climbers blinded by the sun's reflection until they nearly stumbled into it.Correct answer to me, and it didn't change too much the meaning!
(D) Nearly stumbling into the crevasse, the climbers, blinded by the sun's reflection, found it all but invisible.
They put the wrong subject matter
Nearly stumbling into the crevasse as what caused the event.
(E) All but invisible, the climbers nearly stumbled into the crevasse, blinded by the sun's reflection.
The climbers
AIN'T invisible, the crevasse is.
hope I've made a clear explanation for that.
