Net refers to the difference between what is received (absorbed) and what is spent (radiated).
To be a Net radiator the temperature of the body must be higher than that of the surroundings.

I think this is answer A, because of the word 'net'. All objects radiate energy, but they also absorb it from their surroundings. When an object radiates more energy than it absorbs, it would be a net radiator of energy. This would be when its kinetic energy (higher temperature) is greater than its surroundings (lower temperature).

Hi. I think c because ALL objects above absolute zero radiate energy.
