B. Fungi
Plants normally make their own food by the process of photosynthesis. Plants take in water through the roots from the ground, absorb sunlight during the day and take in carbon dioxide from the air to make their nutrients. So plants are normally autotrophic in nature. Animals on the other hand consume plants as well as other animals to produce nutrients. So animals are mostly heterotrophic in nature. Fungi release enzymes which in turn help in digesting external material. Then the fungi absorb that digested compound that is created by the enzyme.
