Explanation / Answer

Ans)option A-temperature,fatty acid composition,cholesterol

All three of above affect the fluidity of the membrane .With increase in temperature the fluidity of the membrane increases but only upto a certain extent after which it decreases .Cholesterol helps in maintaining the stability and the fluidity of the membrane while fatty acid composition contribute to the fluidity .When the number of the fatty acid increases then the fluidity of the membrane also increases so the fatty acids in the membrane help in increasing the fluidity while the proteins help in maintaining permeability.
