Conduction is the transfer of heat between two objects in direct contact. In this case, the heat is transferred from the hot coffee to the mug, and then from the mug to the hands, by conduction. Convection refers to the transfer of heat via the movement of fluids (e.g. air or water), evaporation and condensation involve phase changes and are not relevant here, and radiation refers to the transfer of heat via electromagnetic waves, which is not a significant factor in this scenario.
