Answer:b.active transport of water into the stele
Step-by-step explanation:
What is a stele in plants?
The stele is the middle part in the plants roots or stem. Water during transpiration is lost not gained to the stem or roots.
Diring transpiration plants losses water in the form of water vapor which is released to the atmosphere from the surface of leaves and from stems.
This process is crucial so that plants can receive carbon dioxide which is vital for photosynthesis and for cooling.
Absorption would be the process that occurs when active water get transported into the stele.
