The correct answer is A) It speeds up and bends away from the normal.

Here's why:

1. When light travels from a medium of higher optical density (like water or glass) to a medium of lower optical density (like air), it speeds up. This is because light travels faster in less dense mediums.

2. The change in speed causes the light to change direction, a phenomenon known as refraction.

3. According to Snell's Law, the light will bend away from the normal (the line perpendicular to the boundary between the two mediums) when it speeds up.

So, in summary, as light enters an optically less dense medium at an angle, it speeds up and bends away from the normal.
