Both X and Y are correct
Explanation:
In X:
The speed of sunshine in vacuum, commonly denoted c, may be a universal physical constant important in many areas of physics. Its exact value is defined as 299792458 meters per second. It's approximately adequate to 300000000 meters per second.
In Y:
Refractive index of a medium depends on nature of medium, temperature of the medium, wavelength of sunshine of sunshine incident thereon.
So, the choice (A) is correct.
