Which is the Odd One Out in the List Below

Question

Which is the odd one out in the list below?
A) Leaf cutter ant
B) Underground fungus garden
C) Gongylidia
D) Symbiodinium
E) Escovopsis

Accepted Answer

Symbiodinium is the odd one out because it refers to a genus of dinoflagellates, which are often associated with coral in a symbiotic relationship, unlike the other options which are all related to the mutualistic relationship between leaf cutter ants, their cultivated fungi, and associated organisms within their colonies.
