GUYS WHATS WRONG!!!!!!!!!!! WHY ISNT ANYONE TAKING THIS UP??

B and E are both possible, depending on where the 7th nerve lesion is.

She clearly has a lesion in the 7th nerve on her left. If the lesion is to the 7th nerve itself after the tast fibers have left, then B is the answer. If the lesion is in the brainstem then both B and E are the answers.

Oops, nevermind, B is the answer. I didn't notice at first the E said "right tongue."
