The Correct Option is A

Solution and Explanation

The nutrition in bacteria is mainly autotrophic and heterotrophic. Phototrophic bacteria contain various pigments to synthesise their own food, while heterotrophic bacteria are dependent on other organisms for food. Parasitic bacteria fulfil their nutrition needs or requirements from the host cell. Slime moulds are saprophytes belonging to Kingdom Protista. Mycoplasma are prokaryotic organisms which do not possess a DNA or a cell wall.
