Final answer:
The characteristic shared by plant and animal kingdoms is that both have cells with a nucleus surrounded by a membrane, indicating they are eukaryotic.
Step-by-step explanation:
The statement that describes a characteristic that can be found in organisms in the plant and animal kingdoms is B. Both have cells that contain a nucleus surrounded by a membrane. This characteristic is indicative of eukaryotic cells, which include not only plants and animals but also fungi and protists. Eukaryotic cells are defined by having a nucleus that houses the cell's DNA and is bound by a nuclear membrane. Additionally, eukaryotic cells contain other membrane-bound organelles such as mitochondria and chloroplasts (in the case of plants). Contrary to statement B, animals and plants are not both autotrophic (statement D), not all reproduce asexually (statement C), and not all are single-celled organisms (statement A).
