Which of the following is the largest practical unit of mass ?

Options

A. Slug
B. A.M.U.
C. Hyperkg
D. C.S.L

Explanation

To determine which of the following is the largest practical unit of mass, we need to analyze the options provided: AMU, HyperKG, and CSL.

### Step-by-Step Solution:

1. **Understand the Units**:
- **AMU (Atomic Mass Unit)**: This is a unit used to express the masses of atomic and molecular scales. It is very small (1 AMU ≈ 1.66 x 10^-27 kg).
- **HyperKG**: This is not a standard unit of mass and is not commonly recognized in scientific literature.
- **CSL (Chandrasekhar Limit)**: This is a theoretical limit for the mass of a stable white dwarf star, approximately 1.4 times the mass of the Sun.

2. **Identify the Largest Unit**:
- Among the options, AMU is the smallest unit of mass, and HyperKG is not a recognized unit.
- The Chandrasekhar Limit (CSL) represents a significant mass in astrophysics, specifically related to stellar objects.

3. **Conclusion**:
- The largest practical unit of mass from the given options is **CSL (Chandrasekhar Limit)**, which is approximately 1.4 times the mass of the Sun.

### Final Answer:
The largest practical unit of mass is **CSL (Chandrasekhar Limit)**.
