I'm going with C as well. It's the only one that accurately describes the underlying physics behind chromatic dispersion. The other options are just off the mark.
Option C sounds spot on to me. That's exactly what chromatic dispersion is all about - different wavelengths traveling at different speeds within the fiber. Simple and straightforward.
