The correct option is B Facial

The tongue has been divided into three parts called as anterior two third part, posterior one third part and the base of the tongue. There are different nerves for taste and sensation in the parts of the tongue. The nerve responsible for taste in the anterior two third part of the tongue is the chorda tympani branch of the facial nerve. The nerve responsible for sensation in this part is a lingual branch of the mandibular division of the trigeminal nerve.

So, the correct answer is option B.
