The molecules in object A possess a higher average kinetic energy than those in object B. Thus:

Heat could transfer from object B to object A.

Heat could transfer from object A to object B.

The molecules in object A are vibrating less than in object B.

The temperature of object B is higher than object A.

Answer: Option (b) is the correct answer.

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.

2nd option

Heat could transfer from object A to B

The reason : higher kinetic energy means the particles in A are moving / vibrating faster. This is a reason due to hight temperature.
