I. As the diameter of axons increases, the speed at which impulses are conducted increases.
II. There is a negative correlation between animal size and the speed at which impulses are conducted.
III. Saltatory conduction in myelinated neurons is slower than the speed at which impulses are conducted in non-myelinated neurons.
A. $II$ and $III$
B. $I$, $II$ and $III$
C. $I$ and $II$
D. $I$ only
