Answer :
The best and most correct answer among the choices provided by your question is the fourth choice which is "Heat moves through conduction, convection, and radiation."
Heat transfer is the exchange of thermal energy between physical systems. The rate of heat transfer is dependent on the temperatures of the systems and the properties of the intervening medium through which theheat is transferred. The three fundamental modes of heat transfer are conduction, convection and radiation.

Answer:
Heat moves through conduction, convection, and radiation.
Explanation:
Hello,
In this case, heat transport is possible via conduction, convection and radiation which are defined as follows:
- Conduction: it happens when two or more objects have different temperatures and they are touching each other, thus, the energy is transferred from the hot to the cold object. For example, we can warm our hands by touching hot receptacles or objects.
- Convection: it occurs when a flowing fluid gets in contact with a surface at a different temperature, causing the heat transfer from the hot to cold region. For instance, when the air is freezing, it cools us down as we "provide" heat to it.
- Radiation: it occurs when a heat body transfers energy to its surroundings by the creation of heatwaves which are released due to the temperature difference with its surroundings.
Best regards.
