Both are adapted to aerobic environments.
B
Both lack mitochondria.
C
Both have a single flagellum.

E
Both lack plastids.
Verified step by step guidance1
Understand the characteristics of diplomonads and parabasalids. Both are groups of protists that belong to the supergroup Excavata.
Recall that diplomonads and parabasalids are adapted to anaerobic environments, not aerobic ones. This eliminates the option related to aerobic adaptation.
Note that both diplomonads and parabasalids lack typical mitochondria. Instead, they have modified mitochondria: diplomonads have mitosomes, and parabasalids have hydrogenosomes.
Consider the flagella: diplomonads typically have multiple flagella, while parabasalids have a different flagellar structure, so the option about a single flagellum is incorrect.
Diplomonads are known for having two nuclei, but this is not a characteristic shared with parabasalids. Therefore, the correct shared characteristic is that both lack plastids.
