Answer:
Option d. The temperature change of iron will depend on its latent heat
Explanation:
If the Calorimetry Principle is taken into consideration which says that in case of no heat loss in the surrounding then the reduction in total amount of heat of a hot body is the same as the rise in the total heat of the cold body.
Therefore, iron's temperature change will not depend on its latent heat and will depend on the the other three mentioned factors:
