pls reply fast

We have that the beam of light that emerges from water into air at an angle that  bends

Away from the normal

Option B is correct

Normal of a Plane

In geometry, a normal is an object such as a line, ray, or vector that is perpendicular to a given object. The normal line to a plane curve at a given point is the line perpendicular to the tangent line to the curve at the point.

Therefore it is seen From the Question Image that

The Beam is NOT bent

But Rather

Away from the normal.

In conclusion

The beam of light that emerges from water into air at an angle that  bends

Away from the normal

Option B is correct
