The correct answer is **C. Sieve tube**. In a dicotyledonous stem, each companion cell is found beside a sieve tube. Companion cells are specialized parenchyma cells, located in the phloem of flowering plants. They help in the functioning of the sieve tubes, which are involved in the transport of sugars and other nutrients in the plant.
