400 ohm impedance is correct because characteristic impedance does not depend on the length of the transmission line.
Here Characteristics Impedance is equal to √ L (inductance) by C (capacitance of line).

The point is impedance is independent of length of transmission line.

But what is L and C?

400 Ω is right because here L in inductance.

How 400 will come? I think 4000 ohm is right.
