Explanation
- A
Transmitting power
(a) Transmitting power. Transmittance is the fraction that passes through; albedo is not transmission.
- B
Absorbing power
(b) Absorbing power. Absorptivity is the complementary idea; a high-albedo surface absorbs little.
- C
Emissive power
(c) Emissive power. Emission (Stefan–Boltzmann) is outgoing thermal radiation, not the reflected fraction of incoming sunlight.
- D
Reflecting power
(d) Reflecting power. Albedo is the fraction of incident radiation reflected by a surface (Earth ~0.3). (d) Official key.
Summary. Official key is (d). Albedo means reflecting power. Transmission, absorption and emission are the other radiometric neighbours.
