Solution

The correct option is C Vacuum, Solid
The speed of light has maximum value in the vacuum because it does not require any medium to travel from one point to another. The speed of sound is maximum in solids because in solids the vibrations are transferred from one atom to another very quickly as they are very closely packed in solids.
