Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Kingdom Protista includes all unicellular and colonial eukaryotes, e.g., Euglena, Diatom, protozoans etc. These unicellular organisms do not show prokaryotic behavior, as they also contain the nucleus and other membrane-bound cell organelles. A distinction between unicellular and multicellular organisms is not possible in case of algae in Whittaker's system. It is because of this that unicellular green algae have not been included in kingdom Protista.
Hence the correct option is B.
