"Sunlight is an electromagnetic wave carrying energy that is absorbed by the skin."

Sunlight (especially UV) is electromagnetic radiation; its photons deliver energy to skin cells when absorbed, producing heat and causing molecular/DNA damage that leads to sunburn. Options claiming sunlight is mechanical or that it gains energy in transit are incorrect.
