4. root pressure
5. active transport

Answer:

Option 3. cohesion transpiration is the correct answer.

Explanation:

Plants release water through transpiration while cohesion is responsible for moving more water throughout the xylem. When the water evaporate through the stomata, more water is pulled from roots into stem and eventually reach the leaf this process is called transpiration-cohesion theory.  (More explanation in attached Picture)
