C
Explanation:
This is because glass (2400 kg/m^3) is denser than water (1000 kg/m^3). Water has a refractive index of water is 1.33 while that of glass is 1.54. This means that because the light is traveling from a medium of lower to higher refractive index, it will slow down and most of it will be reflected back into the water medium.
