About 0.55 million or 550,000 years ago the earliest South Asian river dolphin evolved.
About 0.5 million years ago the South Asian dolphin evolved due to different environmental conditions. South Asian dolphin have very flexible necks due to no fusion of their neck vertebrae. They are using echolocation to navigate and search for prey.
Research indicates that South Asian dolphin diverged from a common ancestor around 550,000 years ago that lives in the Indus and Ganges basins so we can conclude that the South Asian dolphin evolved around 0.55 years ago.

c. osmotrophs
d. saprozoic feeders
Answer:
The correct answer will be option-B.
Explanation:
Protist is the group of the organism which is eukaryotes but nither considered true animals, fungi and plants.
Their mode of nutrition is either osmotrophic or phagotrophic. The phagotrophic feeds on the macroparticles like organic particles by surrounding the particle and swallowing it through phagocytosis. The ingested particle gets digested inside the body pf the organism. The phagotrophic organisms are like amoeba and dinoflagellates.
Thus, Option-B is the correct answer.
