Answer: D) A car with the windows rolled up gets very hot on a summer day.
A radiation can be defined as the transmission of energy in the form of waves, particles or rays through space or through a material medium. A radiation is being transmitted from one source till it reaches it's destination. A radiation transfers heat energy. A car with the windows rolled up gets very hot on a summer day would be evidence that heat was transferred by radiation because the glass pane of the window of the car being transparent will absorb the heat energy coming from the solar radiation.
