Correct Answer : Option d

Explanation
An ecotone is a transitional area or boundary between two different ecological communities or ecosystems. It is a region where different ecosystems meet and often contains species from both ecosystems, as well as unique species adapted to that specific transition zone.

Marshlands: Marshlands are transitional areas between land and water ecosystems, typically found where freshwater meets land. This makes them an example of an ecotone because they serve as a boundary between aquatic and terrestrial environments.

Mangrove forests: Mangrove forests are found along coastal regions, where salty seawater meets freshwater from rivers. They are an ecotone between marine and terrestrial ecosystems, supporting unique species that thrive in this boundary zone.

Estuaries: Estuaries are coastal areas where freshwater from rivers meets saltwater from the ocean. They are one of the most well-known examples of an ecotone because they form a transition between aquatic and terrestrial ecosystems, supporting a diverse range of species.

Mountain ranges: Mountain ranges also act as ecotones, where different types of ecosystems are found at various altitudes. For instance, at higher elevations, the ecosystems transition from forests to alpine or tundra environments, creating a boundary between distinct ecological zones
