Aquatic species feel more comfortable in winter than in summer because -
Options:
A .  
% of O2 in air decreases in summer due to high temperature
B .  
Atmospheric pressure decreases in summer leading to reduced solubility of gases in water
C .  
Solubility of gases in water decreases as the temperature increases due to increased Henry’s constant
D .  
Aquatic species feel skin burn due to increased temperature of the water.
Answer: Option C : C
According Henry’s law of solubility of gases - P=KHX With increase in temperature increases, thus ‘x’ decreases given the partial pressure of O2 remains same.
