Which type of rights allows a property owner to utilize water bodies adjacent to their land?

The correct answer is littoral rights, as these rights specifically pertain to properties located along large bodies of water, such as lakes, oceans, and seas. Littoral rights grant property owners the use and enjoyment of the shoreline, which includes activities like swimming, boating, and fishing, as well as a claim to the water itself, although they do not own the water.

In contrast, riparian rights concern properties adjacent to flowing bodies of water, such as rivers and streams. These rights include the ability to use the water for activities like irrigation and recreation, but they are different from littoral rights due to the nature of the water body involved.

Aquifer rights relate to the rights over groundwater sources, which are not applicable in this context, as they deal with water beneath the surface rather than adjacent to the land. Alluvial rights are related to the accumulation of soil deposits from water flow, not the utilization of water bodies.

Therefore, in this context, littoral rights are the correct choice for property owners dealing with adjacent water bodies, while the other types of rights serve different scenarios regarding water use and ownership.
