A heating band was placed around the stem of a plant at a height of $1\,\text{m}$ above the ground and left in position for $10$ minutes. In what way will warming a short part of the stem to $60^\f$ change the movement of phloem sap and xylem sap between the roots and leaves?

- Bphloem: transport continues; xylem: transport stops
- Cphloem: transport stops; xylem: transport continues
- Dphloem: transport stops; xylem: transport stops
