"The amount of time of contact, the area of contact, and the specific heats of the substances" (the second choice).

Reason: heat transferred depends on how long the bodies are in contact, the area through which heat can flow, and the materials' specific heats (which determine how much temperature change a given heat causes). Other important factors (not listed) include the temperature difference and the thermal conductivity of the materials.
