Dictyostelium Discoideum Straddles the Boundary Between Unicellular and Multicellular

Dictyostelium discoideum straddles the boundary between unicellular and multicellular.Its feeding phase consists of individual amoeba-like cells that move independently,feeding on bacteria.When the food runs out,cells begin to aggregate into a multicelled structure.The cells differentiate into a base,stalk,and spores;only the spores survive to colonize a new habitat.What is the advantage of forming spores?

A) The spores will eat the other cells.
B) The spores are photosynthetic.
C) Spores are smaller and can be transported to new habitats.
D) Spores can mate with other species.
E) Spores have flagella and can swim to new habitats.
