Match List I with List II :

(IV) Attraction towards polar surfaces

Choose the correct answer from the options given below :

Accepted Answer

D. 1. This question tests the meaning of key terms related to the **physical properties of water** that are important in plant water transport.

2. **Cohesion (A)** refers to the **mutual attraction between water molecules** themselves, which helps water form a continuous column inside the xylem. So A matches (II).

3. **Adhesion (B)** refers to water's **attraction towards polar surfaces**, such as the walls of xylem vessels, which helps water stick to the vessel walls as it rises. So B matches (IV).

4. **Surface tension (C)** arises because water molecules at the surface are **more attracted to each other in the liquid phase** than to the air above, creating a "skin-like" effect. So C matches (I).

5. **Guttation (D)** is the process where **excess water is lost in liquid form** (as droplets) from the edges of leaves, typically when root pressure is high and transpiration is low. So D matches (III).

6. Combining these: A-II, B-IV, C-I, D-III.

7. Hence, the correct answer is **D**.
