B Correct answer
Explanation

In thermodynamics, a perfect black body is an idealized physical body that absorbs all incident electromagnetic radiation regardless of wavelength or angle of incidence. Black holes are considered the closest physical approximation to perfect black bodies because their event horizons trap all radiation. The term 'black body' in physics refers to this ideal absorber, not actual black objects like buffalo or black paint.
