Why Is the Surface Area of a Gecko's Foot So

Multiple Choice

Why is the surface area of a gecko's foot so extensive?

A) A gecko,like all amphibians,needs extensive surface area under foot for stability on land as well as mobility in water.
B) A gecko's foot acts like a large dipole and thus allows for ion-dipole interaction in water.
C) The greater the surface area the greater the number of induced dipole-induced dipole forces of attraction that can occur between the gecko's foot and the surface.
D) The extensive surface area,once charged by the gecko's body,allows for the dipole-dipole attraction of every contact surface.
