Final answer:
The broiler with a pan will receive a flow of heat directly from the bumeron.
Step-by-step explanation:
Heat will spontaneously flow from the hotter object (bumeron) to the colder object. In this case, the other object that will receive a flow of heat directly from the bumeron is the broiler with a pan (option c), assuming it is at a lower temperature than the bumeron. The pan annealed to 100°C (option b) will not receive a direct flow of heat since it is at a higher temperature than the bumeron.
