Read the passage and answer the following question.
Wet mounts of three living samples of Elodea cells are prepared for viewing under the light microscope. Each slide is mounted with a different solution and viewed after 5 minutes.
Sample A - Elodea + 5 drops of 10% $\displaystyle NaCl$
Sample B - Elodea + 5 drops of isotonic saline
Sample C - Elodea + 5 drops of distilled water

The movement of sap within the xylem is increased by
II. Humidity increases in the surrounding air.
III. Root endodermis prevents ions from entering the xylem.
