Detailed Solution

(A) is true. Altitude sickness is a condition that occurs when a person ascends to high altitudes too quickly and their body does not have enough time to acclimatize to the changes in atmospheric pressure and oxygen levels. This leads to various symptoms, such as breathing difficulty and heart palpitations.
(R) is true. At higher altitudes, the atmospheric pressure decreases, resulting in lower oxygen availability.
(R) explains (A). At higher altitude, breathing rate increases due to the body’s attempt to cope with the decreased oxygen levels by increasing respiratory drive.
The body’s attempt to pump more blood to compensate for the decreased oxygen can result in palpitations or the perception of a racing heart
