Explanation:

• Convection is heat transfer by fluid movement (liquids/gases), not via electromagnetic waves.
• Radiation is energy transfer through electromagnetic waves (like light, infrared) that travel at the speed of light.
• Conduction is heat transfer through direct contact of particles, no electromagnetic waves involved.

So the correct option is Radiation.

Answer:

b. Radiation
