Option-(D): The process of digestion is not one of the factors in the efficiency,(while efficiency is the required set of data or results which provides us with the ratio between the total input to the level of output received inside the system.)

There are certain process which are required to have the optimum level of the different elements inside the human body and for that reason the intake of nutrients along with the production of the optimum level of energy for the living being to develop and grow is related to them.While, the digestion is the mechanism through which the food gets the required treatment in order to absorb the required elements by the body and excretion of the rest of the waste products, but it is not one of the factor for efficiency as digestion itself involves the different metabolic activities to achieve its main purpose inside the living body.
