Explanation:

An open system exchanges both matter and energy with its surroundings. The Earth receives energy from the Sun (as sunlight) and releases energy (as heat). The first option is incorrect because Earth does release energy. The second option is wrong as Earth does absorb energy (from the Sun as sunlight).

The Earth receives energy from the Sun as sunlight and releases energy as heat.
