When two bodies are in thermal equilibrium, it means they are at the same temperature, and there is no net heat flow between them. This does not necessarily imply they must be in thermal equilibrium with a third body, that there must be a net heat flow (which contradicts the definition of thermal equilibrium), that they must be at different temperatures (they are at the same temperature in thermal equilibrium), or that some physical property must be changing. Therefore, none of the provided options correctly follows from the premise that two bodies are in thermal equilibrium.
