The best example of radiation among the options given is "You warm your hands by sitting near a campfire".

Here's why:

Radiation is the transfer of energy through space without the need for a medium (like air, metal, or water). This is how the sun's energy reaches us.

In the example of warming your hands by a campfire, the heat is transferred from the fire to your hands through the air, but not by heating the air. Instead, the energy is radiated out from the fire in all directions and some of it reaches your hands. This is a direct example of radiation.

The other examples involve conduction (transfer of heat through a solid medium, like the metal of a kettle) and convection (transfer of heat through a fluid medium, like the air in a hot air balloon or the water in a kettle).
