The first option is correct: the objects must be different temperatures and they must be in contact.
Explanation: Conduction is heat transfer by direct contact between materials; it requires a temperature difference to drive heat flow. If both objects are the same temperature there is no net conduction, and if they are not touching conduction cannot occur (insulators slow conduction but do not replace the need for contact and a temperature gradient).
