Option D is the correct answer because to “erase “ means to rub out or remove all the traces off.
While all the other options have something to do with cutting off,
Option A, shave means to cut from the surface of something.
Option B , chop means cut (something) into pieces with repeated sharp blows of an axe or knife.
Option C, whittle means carve (wood) into an object by repeatedly cutting small slices from it, since the other three option involve cutting while erasing doesn’t involve cutting, option D is the correct answer.
