Answer & Explanation
The correct answer is Option D: D) It is impossible to open the victim's mouth.
Mouth-to-nose respiration is a crucial alternative technique indicated when the victim's mouth cannot be opened due to significant facial trauma, jaw injuries, or foreign body obstruction. This ensures ventilation is still possible, maintaining oxygenation until advanced medical care is available.
