Why is the surface area of a gecko's foot so extensive?
A. A gecko's foot acts like a large dipole and thus allows for ion-dipole interaction in water.
B. A gecko, like all amphibians, needs extensive surface area under foot for stability on land as well as mobility 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.
