Correct answer: B — Between internal oblique and transversus abdominis

The TAP plane lies between internal oblique and transversus abdominis. Cricothyroid membrane is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Internal superior laryngeal nerve is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Epidural space is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Phrenic nerve is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. In Primary FRCA anatomy, the tested structure should explain the block, airway sign or regional complication in the stem.
