The best answer is C, an emergency surgical airway needs to be established (cricothyroidotomy).
Here's Why: Although the basic recommendations for un-obstructing an airway are most often successful, there are times where early, non-invasive techniques fail. While many health care professionals do not have specialized surgical training, performing an emergency cricothyroidotomy is relatively easy to learn and perform. Many EMS systems and mid-level training programs are available to teach the required skills. Very little equipment is required, and early implementation is life-saving.
