The correct answer describes a desert as "an extremely dry area with little water and few plants." This definition accurately captures the essential characteristics of a desert, which is typically defined by its low precipitation levels—often less than 10 inches annually—and sparse vegetation. Deserts can be found on every continent and are characterized not only by their arid conditions but also by the unique ecosystems that have adapted to survive in such challenging environments.

The other options do not align with the common understanding of what a desert is. Deserts are not large areas of ocean water or narrow inlets of the sea; those descriptions pertain to coastal features and marine geography. Similarly, the term "principal land masses of the earth" refers to continents rather than a specific type of ecosystem. Thus, the definition provided in the correct answer pinpointing the dryness and low plant life distinctly defines the concept of a desert.
