Answer:
I believe the correct option is ''O hydrosphere and biosphere''
Explanation:
''A blue whale swims in the ocean.''
breaking up the sentence, ''A blue whale''. That is apart of the Biosphere as it includes all living orginisms, including said blue whale.
''Swims In the Ocean'', the Ocean is made up of the earths water, which sudgests the Hyrosphere as it is all waters on the earth's surface.
