You are presented with the question "Aquatic animals in water use webbed feet due to what?" and the following answer choices: 
- ability to sense light
 - principals of aerodynamics
 - kinetic energy
 - swimming slower
 - refraction of light
 - poor swiming
 - bending light rays
 - dynamic relationships

Now knowing that webbed feet are used for moving faster through water by aquatic animals and aquatic animals moving through water are also subject to the principles of aerodynamics, choose the best answer.
