- CA-IV, B-III, C-II, D-I
- DA-III, B-I, C-IV, D-II
Solution
Cohesion
- This is the mutual attraction between water molecules. This happens due to the presence of polar bond and polar interaction.
Adhesion
- When water molecule bonds with some other polar compound, like lignin of the xylem wall, this interaction is called adhesion.
Surface tension
- Surface tension represents water molecules are attracted to each other in the liquid phase more than to water in the gas phase.
Guttation
- The loss of impure water in the liquid droplet form from the hydathodes in some herbaceous plants is called guttation. This happens due to root pressure.
Hence, the correct answer is option: 'B'.
