Heat Transfer Questions

Q.  What is the reason behind the fact that the thermal resistance of hollow cylinder for convection decreases with increase in the thickness of the insulation?

a. volume of insulating material increases and it transfer less heat energy
b. increase in surface area of the cylinder leads to less convective heat transfer
c. increase in surface area of the cylinder leads to more convective heat transfer
d. none of the above
