Answer: Option (b) is the correct answer.
Step-by-step explanation:
When two objects of different temperature are kept in contact with each other then exchange of heat energy will take place between the two objects until a dynamic equilibrium is reached between the two object.
So, heat will transfer from a hooter object to a colder object.
For example, when molecules in object A possess a higher average kinetic energy than those in object B, then heat will be transferred from object A to object B.
Thus, we can conclude that in the given situation heat could transfer from object A to object B.
