Answer
B. Radiation only
Explanation
Energy can be transferred in three basic ways: conduction, convection, and radiation. Conduction refers to the energy transfer between materials that are in direct contact, mostly observed in solid materials like metals but not limited to it. Convection is the energy transfer that takes place when warmer particles move from one place to another, causing the transfer of energy, mostly observed in liquids and gases. Last but not least, radiation is an energy transfer that doesn't require any medium and can travel through empty space (vacuum). Therefore, in a scenario where there are no particles (like in vacuum), the only form the energy transfer can happen is through radiation, not conduction and convection.
