Radiation
Not really. sunburn is not caused by heat at all, but by overexposure to ultra-violet (specifically UV-B) radiation. It causes damage directly to the DNA rather than heat damage to the skin.
While the answer 'radiation' is technically correct as UV is a type of radiation, sunburn is not caused by heat transfer at all.
Radiation is the type of heat transfer that occurs in the form of waves. This transfer of heat can occur through empty space and does not require a medium. Examples include sunlight and heat transfer from a fire.
Convection is the type of heat transfer that occurs in only liquids and gases. It involves the transfer of heat through the movement of the fluid molecules due to differences in their density and temperature.

Heat transfer by Brownian motion takes place only in fluids (liquids, gases, and plasmas).
Conduction and radiation.
Convection is the type of heat transfer that occurs only in gases or liquids. It involves the movement of the heated fluid itself, which carries heat energy from one place to another.
Conduction is the type of heat transfer where heat energy is carried by particles. It occurs through direct contact between particles, causing them to transfer heat energy from one another.

Conduction is the type of heat transfer that occurs when heat is transferred through a substance. In conduction, heat moves from higher to lower temperature regions within the substance.
Conduction is the primary heat transfer process that occurs when eggs cook in a hot pan. Heat is transferred from the pan to the eggs through direct contact.
