Correct Answer is A

Explanation

Rationale:
A. In respiratory acidosis, CO₂ accumulates in the blood due to hypoventilation, lowering the pH. The kidneys compensate by retaining HCO₃ (bicarbonate), which helps buffer excess hydrogen ions and raise the pH toward normal.
B. Hypoventilation causes or worsens respiratory acidosis by increasing CO₂ levels, so it is not a compensatory response.
C. Excreting HCO₃ would lower the pH further and worsen the acidosis, so this is incorrect.
D. Hyperventilation helps reduce CO₂ levels but is a respiratory response, not a renal compensatory mechanism. Compensation for respiratory acidosis primarily occurs via the kidneys, not the lungs.

Correct Answer is ["1637"]

Explanation

Rationale:

Military time, also known as the 24-hour clock, is a method of telling time where the hours of the day run from 00:00 to 23:59, rather than resetting at noon and midnight like in standard 12-hour time (AM/PM). 4:37 PM in military time is 1637.
