What is the best evolutionary explanation for the presence of flagellated cells in the life cycles of chytrids and their absence from other fungi?
A) Chytrids are specialized fungi that evolved this trait from fungal ancestors that lacked flagellated cells.
B) The presence of flagellated cells in chytrids shows that they are more closely related to animals and choanoflagellates than to actual fungi.
C) Chytrids evolved flagellated cells as an adaptation to living in water.
D) Flagella have evolved repeatedly in many different eukaryotic groups,and their presence is evolutionarily meaningless.
E) Flagellated cells in chytrids are a remnant of the common ancestry of fungi,animals,and choanoflagellates that has been lost in other fungi.

Flagellated cells in chytrids are considered a remnant of the common ancestry shared by fungi, animals, and choanoflagellates, which has been lost in other fungi. This suggests that chytrids retain an ancestral trait that was present before the divergence of these groups.
