Answer
A. Radiation
Explanation
Thermal energy from the sun reaches the Earth and objects on it, such as your face, primarily through radiation. This process involves energy being emitted as electromagnetic waves, which travel through the vacuum of space and are absorbed by the skin, resulting in the sensation of warmth. Conduction and convection require physical contact or fluid movement, respectively, which are not applicable in this context.
