Given data:
Surface temperature of the radiator, T = 60 °C

We are required to calculate the heat flux at the surface of the radiator if it behaves as a black body.

Formula used:
Stefan-Boltzmann law: Q = σAT⁴
where Q = heat flux, σ = Stefan-Boltzmann constant = 5.67 x 10⁻⁸ W/m²K⁴, A = surface area of the radiator, T = temperature in Kelvin.

Calculation:
Surface temperature of the radiator, T = 60 °C = 333 K
Area of the radiator, A = 1 m² (Assuming a flat surface)
Using the Stefan-Boltzmann law, we have:
Q = σAT⁴
Q = 5.67 x 10⁻⁸ x 1 x 333⁴
Q ≈ 697.2 W/m²

Therefore, the heat flux at the surface of the radiator is 697.2 W/m², which is option A.
