Material C is the most dense.

I agree with your answer of D.

If the material is more dense, then the speed that light travels through it must get slower. In Choice D, this fact is shown.

The denser material (Material D - 124) has a slower speed than the other option (Material A - 140). This is only choice that follows this pattern.
