Answer:
The correct option is D.
Technical efficiency in production means that as few inputs as possible are used to produce a given output. Economic efficiency means using the method that produces a given level of output at the lowest possible cost.
Step-by-step explanation:
Technical efficiency is the degree to which the actual output of a production unit approaches its maximum. For example, a firm is said to be technically efficient if a firm is producing the maximum output from the minimum quantity of inputs such as labour, technology and capital. In technical efficiency, unemployment of resources are not required.
Economic efficiency is concerned with producing at the lowest point of the short run average cost curve. Economic efficiency assumes minimum cost for a production of goods or services, maximum output, and maximum surplus for the operation of the market. Economic efficiency indicates a balance between profit and loss.
