D. `F_(CS)gtF_(CL)=F_(CG)`

Explanation

To solve the question regarding the cohesive forces of solids, liquids, and gases, we need to analyze the nature of these forces in each state of matter.

### Step-by-Step Solution:

1. **Understanding Cohesive Forces**:
- Cohesive forces are the intermolecular forces that hold molecules of the same substance together. These forces vary in strength depending on the state of matter.

2. **Cohesive Forces in Solids**:
- In solids, the molecules are tightly packed together. The intermolecular forces are very strong due to the close proximity of the molecules. Therefore, the cohesive force of solids (F_CS) is the strongest.

3. **Cohesive Forces in Liquids**:
- In liquids, the molecules are still close together but not as tightly packed as in solids. The intermolecular forces are weaker than those in solids. Hence, the cohesive force of liquids (F_CL) is less than that of solids but stronger than that of gases.

4. **Cohesive Forces in Gases**:
- In gases, the molecules are far apart and move freely. The intermolecular forces are very weak due to the large distances between the molecules. Therefore, the cohesive force of gases (F_CG) is the weakest.

5. **Comparing the Cohesive Forces**:
- Based on the analysis:
- F_CS (cohesive force of solids) > F_CL (cohesive force of liquids) > F_CG (cohesive force of gases)
- This leads us to conclude that the correct order of cohesive forces is:
- F_CS > F_CL > F_CG.

6. **Final Answer**:
- The correct option is that the cohesive force of solids is greater than that of liquids, which is in turn greater than that of gases.
