When is thermal equilibrium achieved between two objects?

a. when the particles in one object have more kinetic energy

b. when one objects is hotter than the other

c. when both objects have the same temperature

It’s C for sure I took this awhile back but I still remember... so thermal equilibrium is when to object have the same temperature due to them touching and transferring temperature for example if we have two metal blocks and one them is hotter than the other when you put them together the heat transfers and makes them both the same temperature.
