Explanation:
Kingdom Protista
A. Plantae is the kingdom of multicellular and photoautotrophic organisms which grow indefinitely. The body is differentiated into root, stem and leaves. Mode of nutrition is autotrophic due to presence of chlorophyll. Cell wall is present which is made up of cellulose.
B. Fungi is a kingdom of heterotrophic organisms. Fungi have filamentous forms called hyphae.
C. Kingdom Animalia comprises multicellular organisms having eukaryotic cells. Cell wall is absent and the mode of nutrition is heterotrophic.
D. Kingdom Protista consists of unicellular eukaryotic organisms. Cell wall may or may not be present. A well defined nucleus is present. The cytoplasm contains a variety of membrane bound organelles like mitochondrion, plastids, endoplasmic reticulum, Golgi bodies. Mode of nutrition may be autotrophic or heterotrophic depending upon the organisms.
E. Domain bacteria consists of prokaryotic organisms which lack a well defined nucleus and membrane bound organelles. Mode of nutrition is autotrophic ( photosynthetic and chemosynthetic) and heterotrophic.
So, the correct answer is Kingdom protista.
