Answer B is incorrect.
An Un-cut tube is long and is advanced beyond the stoma.
An Aintree catheter is extremely useful in these situations and can deliver oxygen, detect CO2, allow jet ventilation (with care) and act as a bougie to facilitate 'rail-roading' of a new tube into the airway. A small (4.5 mm or less) endoscope will pass through the lumen and allow it to be guided under direct vision.
If the stoma is difficult, the cricothyroid membrane may be identified as it is anterior in the neck. Emergency oxygenation can be delivered this way.
