Only this is correct: "Thermal energy from the coffee is transferred to the mug."
Explanation: heat flows from the hotter object (coffee) to the colder one (mug) until they reach the same temperature. That means the coffee's average kinetic energy (temperature) decreases and the mug's average kinetic energy increases.
