• C. Have more RBCs and their haemoglobin has a lower binding affinity to $O_2$
• D. Are not physically fit to play games like football

Answer 1

The correct option is A Suffer from altitude sickness with symptoms line nausea, fatigue, etc

People who have migrated from the planes to an area adjoining Rohtang pass about six months back suffer from the altitude sickness because in higher altitude the pressure of air decreases and there are fewer molecules of oxygen available in the given volume. So, there will not be enough oxygen to take inside the body. Due to this, faster breathing starts. The body will feel exhausted as more carbon-dioxide is accumulated. This will cause fatigue and nausea. Hence, the correct answer is ‘Suffer from altitude sickness with symptoms like nausea, fatigue etc.’
