speed of light is not constant as it moves from medium to medium. When light enters a denser medium (like from air to glass) the speed and wavelength of the light wave decrease while the frequency stays the same. How much light slows down depends on the new medium's index of refraction.
Hence A is correct

The correct answer is (a)  frequency .It doesn't change with medium because the number of waves never changes with any change in medium.

Frequency is due to the thing that emits or creates waves. It is not closely related to waves but it is mainly related to the ' thing' that creates it. So, change in medium affects the wave and it's properties like wavelength and velocity and amplitude but the frequency remains unchanged. 
Thus option A is correct.
