B. b. स्थैतिक घर्षण
C. c. लौटनिक घर्षण
D. d. सब समान होंगे

Answer

To determine which type of friction is the highest among the given options, we need to understand the different types of friction and their characteristics. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Types of Friction
There are three main types of friction:
1. **Static Friction (FS)**: This occurs when an object is at rest and a force is applied to it, but it does not move. It is the friction that needs to be overcome to start moving the object.
2. **Sliding Friction (Serpil Friction, FSL)**: This occurs when an object is sliding over another object. It is less than static friction but more than rolling friction.
3. **Rolling Friction (FR)**: This occurs when an object rolls over a surface. It is the least among the three types of friction.

### Step 2: Compare the Magnitudes of Friction
- **Static Friction** is the highest because it prevents motion until a certain threshold force is applied.
- **Sliding Friction** is in the middle, as it acts when the object is already in motion.
- **Rolling Friction** is the lowest because it involves less contact area and is easier to overcome.

### Step 3: Conclusion
Based on the understanding of the types of friction:
- **Static Friction (FS)** has the highest value.
- **Sliding Friction (Serpil Friction, FSL)** is moderate.
- **Rolling Friction (FR)** is the lowest.

Thus, the answer to the question "निम्न में से किस घर्षण का मान सर्वाधिक होगा" is **Static Friction (FS)**.

### Final Answer:
**Static Friction (FS) is the highest among the types of friction.**
