During your Emergency Medicine rotation at Massachusetts General Hospital, a local Basic Life Support (BLS) rescue crew brings in a "code" (cardiac arrest patient). The patient is an obese 55 year old male with a history of HTN (hypertension) and angina pectoris (chest pain). The EMS crew is still aggressively working the patient via chest compressions and rescue breaths with a BVM (bag valve mask). As a observant student you note to your supervising Resident that the patient only has an OPA (oropharyngeal airway) adjunct inserted. Noticing your enthusiasm, your resident decides to assign you with the responsibility of removing the OPA and performing an intubation. You correctly take your mac blade and rest the tip of the blade between the root of the patient's tongue and the epiglottis. You then smoothly pass the ET (endotracheal) tube between the patient's vocal cords. During this procedure, what is the name of the groove in which you place your Mac blade?

Your first semester friend runs in and says "I couldn't find the local anesthetic, what if we just cut the nerves that supply sensation to the area inside the larynx where the pen pokes through?" You reply:
- A.
  
  Great idea, let me just go to the tracheoesophageal grooves and clip the recurrent laryngeal nerves.
- B.
  
  Great idea, right behind the sternothyroid muscles I can clip the external laryngeal nerves before it pierces into the inferior pharyngeal constrictor.
