B) Keep oxygen tanks 4 feet away from an electric stove. Oxygen tanks should be kept at least 8 to 10 feet away from heat sources, including electric stoves.
C) Store oxygen tanks upright. Oxygen tanks should always be stored upright and secured to prevent them from falling and causing injury or damage.

Explanation
A) Endotracheal tube. An endotracheal tube is invasive and used for patients who require mechanical ventilation, not for simple airway maintenance.
B) Partial rebreather oxygen mask. A partial rebreather mask is used to deliver oxygen, not to maintain airway patency.
