The optical density of turpentine is higher than that of water while its mass density is lower. Figure shows a layer of turpentine floating over water in a container. For which one of the four rays incident on turpentine in figure, the path shown is correct?

In the figure, the path shown for the ray 2 is correct. The ray suffers two refractions: At A, ray goes from air to turpentine, bending towards normal. At B, ray goes from turpentine to water (i.e., from denser to rarer medium), bending away from normal. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/70c0b15e2d49cffb8db4d1b65df60ca8-.png" />
