Respuesta :

Answer:

A

Explanation:

Detailed balance, i.e. 2nd law of thermodynamics, requires a relationship between absorbing incoming radiation and turning it into heat, versus emitting thermal radiation. A perfect mirror at rest does not absorb any incoming radiation, therefore it is a "whitebody", not a blackbody, and emits no thermal radiation.
