Context triple: [Miramare Marine Reserve, hasFlora, Cystoseira spp.]

A. Posidonia oceanica meadows
Posidonia oceanica meadows are extensive underwater seagrass habitats in the Mediterranean Sea that provide crucial ecological functions such as carbon sequestration, shoreline protection, and biodiversity support.
B. Sargassum natans
Sargassum natans is a free-floating brown alga commonly found in the Sargasso Sea, where it forms extensive mats that provide habitat for diverse marine life.
C. Trenholmensiales
Trenholmensiales is a relatively small and specialized order of fungi within the class Sordariomycetes, characterized by its distinct microscopic features and phylogenetic placement among ascomycetous fungi.
D. Parasponia
Parasponia is a small genus of tropical trees and shrubs notable for being the only non-leguminous plants known to form nitrogen-fixing symbioses with rhizobial bacteria.
E. Togniniales
Togniniales is an order of fungi within the class Sordariomycetes, comprising ascomycetous species often associated with plant material and wood.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
