The entropy is usually defined as the measure of the total thermal energy of a system per unit temperature. This amount of energy is used in performing valuable work. In simple words, it can be said that entropy is related to the disorder or degree of randomness of a particular system. This entropy concept gives proper information regarding the direction along which natural change occurs and is frequently observed in many present-day events.
Thus, the correct answer is option (D).
