Answer:

The correct answer is A. The oxygen concentration will decrease in the blood while holding breath.

Explanation:

  • Long-term breath holding lowers oxygen levels and increases carbon dioxide levels in the body. Due to the altered free hydrogen ion concentration, these cells become abnormally excitable and perform abnormally.
  • The pH and the amount of free hydrogen ions in blood are two factors that profoundly affect the brain regions that regulate breathing.
  • The brain immediately boosts our respiratory drive to take in more oxygen and exhale more carbon dioxide in an effort to restore the normal balance between oxygen and carbon dioxide when it detects the change in pH caused by increasing carbon dioxide.
  • When this defense mechanism is compromised or missing, individuals may experience dizziness, seizures, or brain damage.

Therefore, Raghu's oxygen concentration will decrease while he holds his breath.
