Grey body is defined as a body with constant emissivity over all wavelengths and temperatures.
So, the answer is A grey body.
So, the answer is A grey body.

Emissivity value 1 for black body and 0.8 for grey body but, same for all wave length for grey body so,anawer is grey body.

How come a grey body is emitting more radiation than a black body at any specified temperature?

A black body is a perfect emitter.

If it is so is the answer black body?

No black body is a perfect absorber black body just absorb radiation.

Answer will be black body. For black body emissivity = 1 & absorptivity = 1.

Black body absorptivity is 1 but emissivity 0.

Black body is the right answer.
Because it has absorptivity 1 and emissivity 1 for all wavelength.
While the grey body has max emissivity of monochromatic wavelength.
Because it has absorptivity 1 and emissivity 1 for all wavelength.
While the grey body has max emissivity of monochromatic wavelength.
