The terminal velocity of a spherical body falling through a viscous liquid is given by V = kr^n, where r is the radius of the sphere, and k and n are constants. The values of k and n can be determined by plotting a graph of

1. (A)V versus r
2. (B)V versus \frac{1}{r}
3. (C)\ln V versus \ln r
4. (D)\ln V versus \frac{1}{\ln r}
