Calculation of Moment of Inertia of a Circular Disc
To calculate the moment of inertia of a circular disc about an axis perpendicular to the plane of the disc and passing through its center, we can use the formula:

I = (1/2) * m * r^2
Where:
- I is the moment of inertia
- m is the mass of the disc
- r is the radius of the disc
Given:
- Mass (m) = 0.4 kg
- Radius (r) = 100 cm = 1 m

Substitute the values into the formula
I = (1/2) * 0.4 * (1)^2
I = 0.2 kg m^2
Therefore, the moment of inertia of the regular circular disc of mass 0.4 kg and radius 100 cm about the given axis is 0.2 kg m^2. Hence, the correct answer is option D.
