Yeasts are unicellular fungi that do not produce hyphae. However, they are descended from a common ancestor that did produce hyphae. Which of the following statements explains why yeasts do not produce hyphae?

A)Hyphae require many cells, so a unicellular organism is unable to produce hyphae.
B)Yeasts grow in nutrient-rich environments, so they do not require hyphal growth to reach regions high in nutrients.
C)Yeasts are descended from unicellular bacteria, and hyphal growth is not a characteristic of bacteria.
D)Yeasts are representative of the earliest fungal lineages before hyphal growth evolved in the group.
