Step-by-step explanation:
The term for a narrow land bridge that connects two larger land masses is called an isthmus. The best example of an isthmus is the Isthmus of Panama, which connects North and South America. None of the options provided in the question correctly represent an isthmus or its example. However, the closest answer choice in context would likely be 'd) Isthmus / Maui', but note that Maui is not connected to another landmass by an isthmus; it is part of the Hawaiian Islands archipelago.
An isthmus forms in various ways, such as tectonic movements or sediment accumulation. They are geologically significant because they can influence ocean currents and climates and have played pivotal roles in human migration and trade throughout history.
