The characteristics that can be true about the plant kingdom are:
A. Autotroph
C. Multicellular
E. Cellulose cell walls
Plants are primarily autotrophic organisms that produce their own food through photosynthesis. Most plants are multicellular, and their cell walls are primarily made of cellulose.
Chitin cell walls (B) are characteristic of fungi, not plants, and heterotroph (D) describes organisms that cannot produce their own food, which is not a characteristic of plants.
