$I, II$ and $III$
B
$II, III$ and $IV$
C
$I, III$ and $IV$
D
$I, II$ and $IV$
Solution
Body compensates low oxygen availability at high altitude by increasing $RBC$ production, increasing binding capacity of haemoglobin (through increasing $2, 3-$biphosphoglyceric acid) and increasing breathing rate
