When you are beneath the surface of water and looking upward, light from above is refracted or bent as it passes from the air into the water. This causes a visible distortion in the view of objects above the surface of the water. The extent of this distortion is limited to a cone of approximately 96°. Beyond this cone, the water surface appears dark, and no visible light from above is seen. Therefore, the correct option is A) within a cone of 96°.
