The tensile strength of water / high capillarity is the gift of which properties of water -

Options

A. Cohesion
B. Adhesion
C. Surface tension
D. All

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about the properties of water that contribute to its tensile strength and high capillarity.

2. **Identify Relevant Properties of Water:**
The key properties of water that are relevant to this question are:
- Cohesion
- Adhesion
- Surface Tension

3. **Define Cohesion:**
Cohesion is the attraction between water molecules due to hydrogen bonding. This property allows water molecules to stick together, which contributes to the tensile strength of water.

4. **Define Adhesion:**
Adhesion is the attraction between water molecules and other substances, particularly hydrophilic surfaces. In plants, the xylem vessels are hydrophilic, allowing water to adhere to their surfaces and facilitating its movement.

5. **Define Surface Tension:**
Surface tension is the result of cohesive forces between water molecules at the surface. It is a measure of how much the surface of water can resist external force, and it is particularly high in water due to strong hydrogen bonding.

6. **Combine the Properties:**
The tensile strength of water and its ability to move through capillaries (capillary action) are a result of the combined effects of cohesion, adhesion, and surface tension.

7. **Conclusion:**
Therefore, the correct answer to the question is that the tensile strength of water and its high capillarity are gifts of all three properties: cohesion, adhesion, and surface tension.

**Final Answer:**
The tensile strength of water and high capillarity are the result of the properties of water: cohesion, adhesion, and surface tension. Thus, the answer is "all."
