Final answer:
No, a single iron atom would not be able to conduct heat because it does not have the same properties as the element iron.
Step-by-step explanation:
No, a single iron atom would not be able to conduct heat. Choice c) is the correct option. Heat conduction occurs in metals due to the movement of free electrons. In metals, the positive nuclei are packed closely together, allowing the heat to be easily transferred. A single iron atom does not have the same properties as the element iron, so it would not be able to conduct heat on its own.
