$A$ star emits radiation with maximum intensity at a wavelength of $289.9 \, nm$. What is the intensity of the radiation emitted by the star? (Given: Stefan's constant $\sigma = 5.67 \times 10^{-8} \, W/m^2K^4$,Wien's constant $b = 2898 \, \mu m \cdot K$)

• A
  $5.67 \times 10^8 \, W/m^2$
• B
  $5.67 \times 10^{12} \, W/m^2$
• C
  $5.67 \times 10^{18} \, W/m^2$
• D
  $5.67 \times 10^{16} \, W/m^2$
