Which description fits a wharf?

A wharf is primarily defined as a structure built parallel to the shore, providing a platform for ships to dock. It typically allows for the loading and unloading of cargo and passengers directly from the vessel to the land, facilitating efficient movement between the ship and the shore. The design of a wharf enables it to accommodate vessels of varying sizes and allows for easy access to facilities that may be located on the land side.

In contrast, other options describe different maritime structures or areas. A structure that extends into the water at a right angle refers more to a pier, whereas a dock used for ship repair typically implies a dry dock or repair facility, which is distinct from the primary purpose of a wharf. The space between two piers is simply a navigational or operational area and does not define a wharf’s characteristics. Understanding the specific functionality and positioning of these structures is crucial in distinguishing between them.
