I'm unable to see images. However, I can help explain how light rays behave when they travel from air into oil and water.
When a light ray travels from air (a less dense medium) into oil (more dense than air but less dense than water), it will bend towards the normal as it enters the oil. Then, as it travels from oil to water (from a less dense medium to a more dense medium), it will also bend towards the normal again.
If you can describe the options (A, B, C, D) or how each of the light rays behaves in those options, I can help you determine which one correctly illustrates the behavior of the light ray as it goes from air to oil and then from oil to water.
