The heat from the Sun must pass through the vacuum of space before it reaches the Earth. Which process is illustrated in this example?

The hot atoms will then bump into colder atoms, sharing their heat through conduction, until the bath becomes an even temperature. But because space is a vacuum, there are no liquids or gases to convect heat away from the sun, all the way to Earth. So we can rule out convection.

Explanation:

The question says, the heat of the sun must pass through the vacuum space before it reaches the earth. Which process is illustrated in this example. The correct option is B, that is, radiation. Radiation is the mode of transmission of heat energy as electromagnetic waves through space or through a material medium. Thus, the heat from the sun get to the earth surface through radiation.
