Which of the following is correct about Permeability of free space?

Options

A. It is a scalar quantity
B. Its S.I. unit is T `mA^(-1)`
C. Both (A) and (B)
D. None of the above

Explanation

To determine which statements are correct about the permeability of free space, we can analyze the properties and definitions related to it step by step.

### Step-by-Step Solution:

1. **Definition of Permeability of Free Space**:
- The permeability of free space (often denoted as μ₀) is a physical constant that describes how a magnetic field interacts with a vacuum. It is a measure of the ability of a material (in this case, free space) to support the formation of a magnetic field.

2. **Scalar Quantity**:
