Dinoflagellates (Protists) and Salmonella (Bacteria) Are Tiny, Flagellated Organisms

Dinoflagellates (protists) and Salmonella (bacteria) are tiny, flagellated organisms. One is a prokaryote and one a eukaryote so we know they must differ in the following ways.

A) The Dinoflagellate must be multicellular with membrane-bound organelles while the Salmonella must be unicellular and lacking membrane-bound organelles.
B) The Dinoflagellate must have flagella made up of microtubules and have membrane-bound organelles while the Salmonella must have flagella made of flagellin and lack membrane-bound organelles.
C) The Dinoflagellate must be multicellular with linear DNA while the Salmonella must be unicellular with circular DNA.
D) The Dinoflagellate must have flagella made up of microtubules and circular DNA while the Salmonella must have flagella made up of flagellin and linear DNA.
E) The Dinoflagellate must be multicellular with flagella made up of microtubules while the Salmonella must be unicellular and have flagella made of flagellin.
