Depending on the radiating properties, a body will be white when
(Where a = absorptivity, p = reflectivity, x = transmissivity)

P = 0, x = 0 and a = 1

P=1, T = 0 and a = 0

P = 0, x = 1 and a = 0

X = 0, a + p = 1

Answer : Option B

Explanation :

Depending on the radiating properties, a body will be white when
P=1, T = 0 and a = 0
(Where a = absorptivity, p = reflectivity, x = transmissivity)
