Solution

The correct option is A True
By the Second law of thermodynamics..the heat flows from an higher to lower region in terms of entropy.(Entropy is the measurement of order of disorderness of a system).The entropy of a hot body is more than that of a cold one.
energy will always be transferred from the hotter to the cooler object. The objects will exchange thermal energy, until thermal equilibrium is reached,
Hence statement is true
