Which is a possible reason for the transition of algae from unicellularity to multicellularity?

A.
The transition to multicellularity enabled algae to receive nutrients through the process of photosynthesis.
B.
Through multicellularity, algae were able to move spontaneously in wet environments and find additional sources of nutrients.
C.
The evolution of multicellularity allowed algae to develop traits that kept them close to the land and thus a source of nutrients.

Read the following scenario to answer the following question. over the past 60 years, many amphibian species have experienced significant population declines, and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. when most populations of a wide-ranging amphibian species are lost and the few remaining populations are widely separated, we expect to see that a. the founder effect becomes increasingly important b. microevolution no longer occurs c. gene flow between populations is reduced d. artificial selection becomes a greater factor in microevolution
