Inna dark room with ambient temperature T0,na black body is kept at a temperature T. Keeping thenntemperaturenof the black body constant (at T), sunrays are allowed to fall on the blacknbody through a hole innnthenroof of the dark room. Assuming that there is no change in the ambientntemperature of the room, which ofnnthenfollowing statement(s) is/are correct?

• A. The quantity of radiation absorbed by the black body in unit time will increase.
• B. Since emissivity = absorptivity, hence the quantity of radiation emitted by black body in unit time will increase
• C. Black body radiates more energy in unit time in the visible spectrum
• D. The reflected energy in unit time by the black body remains same.
