Solution
The correct option is A zero Marginal means over and above the total by additional quantity whereas Total Utility is the total satisfaction derived by the consumption of sum of quantities of a commodity. MU is the rate of change in TU.
At the initial level of consumption MU increases and TU also increases but later on there is a saturation point of consumption where MU is ZERO and TU is maximum and remains constant and then after MU starts negative and TU starts declining.
