A ray of light travelling in air goes into water. The angle of refraction will be  smaller than the angle of incidence.

Option (b) is correct.

Explanation:

We know that when a ray of light travels from rarer medium to denser medium, it bends towards the normal.

Since air is rarer medium and water is denser medium,

Therefore, when the ray of right travels from air to water, it will bend toward the normal

Thus, the angle of refraction will be lesser than that of the angle of incidence

Therefore, the angle of refraction will be smaller than the angle of incidence.
