C Correct answer
Explanation
  1. Buccal nerve, also known as the buccinator nerve and the long buccal nerve, usually passes between the two heads of lateral pterygoid to reach the external surface of that muscle.
    1. It then follows the inferior part of the temporal muscle and emerges under the anterior border of the masseter muscle continuing in an anterolateral direction.
    2. At level of the occlusal plane of the mandibular 3rd/2nd molar, it crosses in front of the anterior border of the ramus and enters the cheek through the buccinators muscle.
    3. It is recommended that, therefore, during IAN injection, it is better to give separate long buccal nerve injection.
    4. Better option is 'a' since all other nerves are there in pterygomandibular space.
