Answer 1

The correct option is C <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Ion concentration gradient

In soil, roots actively take up ions which create a difference between ion concentration in roots and soil. To eliminate this difference, water from soil moves into the root.
