Thermal Radiation: Black Body, Stefan & Wien

A body is said to be opaque to the radiation if (a, r and t are coefficient of absorption, reflection and transmission respectively)

Show answer and solution

Answer: (a)

Opaque body transmits nothing: $t = 0$ .
From $a + r + t = 1$ : $a + r = 1$
So the answer is (a).
