B Correct answer
Explanation

Breathing into a paper bag helps treat hyperventilation by re-inhaling carbon dioxide. Hyperventilation causes excessive CO2 expulsion, leading to respiratory alkalosis. The paper bag technique increases CO2 levels in the bloodstream, restoring acid-base balance. It does not treat hypoxia, which requires oxygen supplementation.
