Context triple: [Cyprinodontiformes, notableGenus, Cyprinodon]

A. Epigonichthys
Epigonichthys is a genus of small, eel-like lancelets within the subphylum Cephalochordata, known for their simple, fish-like bodies that provide key insights into early chordate evolution.
B. Entosphenus
Entosphenus is a genus of jawless, eel-like lampreys that includes several parasitic and anadromous species found primarily in North American freshwater and coastal marine environments.
C. Erpetoichthys
Erpetoichthys is a genus of elongated, eel-like bichir fishes native to African freshwater habitats, best known for the ropefish (Erpetoichthys calabaricus).
D. Alewife
Alewife is a major subway station and transit hub in North Cambridge, Massachusetts, serving as the northern endpoint of Boston’s MBTA Red Line and a large park-and-ride facility.
E. Cyprinodontiformes
Cyprinodontiformes is an order of ray-finned fishes that includes killifishes, livebearers, and related small freshwater and brackish species found worldwide.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
