Emissive power question help needed!!!

The question is on emissive power emitted and i have attached it as a file

RELEVANT EQUATIONS

E=stefan boltzmann constant * T^4

ATTEMPT

E=(5.67*10-8) * (923)^4
E = 41151.9

Don't know how to get the wavelength from this
should i use Plancks equation for emissive wavelength

To help the answers are included, its a multiple choice paper

thanks for your help
