Given data:
CO2 = 15%
O2 = 5%
N2 = 80%
Temperature (T) = 200°C
Pressure (P) = 5 bar

Partial pressure of a gas in a mixture is given by Dalton's law of partial pressures, which states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual gases in the mixture.

Partial pressure of CO2 = 15% of 5 bar = 0.15 x 5 = 0.75 bar
Partial pressure of O2 = 5% of 5 bar = 0.05 x 5 = 0.25 bar
Partial pressure of N2 = (100% - 15% - 5%) of 5 bar = 0.80 x 5 = 4 bar

Total pressure of the mixture = 0.75 bar + 0.25 bar + 4 bar = 5 bar

Now, we can use the partial pressure of N2 to find the answer.

Partial pressure of N2 = Total pressure - Partial pressure of CO2 - Partial pressure of O2
= 5 bar - 0.75 bar - 0.25 bar
= 4 bar

Therefore, the partial pressure of N2 in the flue gas is 4 bar, which corresponds to 400 kN/m2 (1 bar = 100 kN/m2).

Hence, the correct answer is option D.
