Answer: D. Decreasing inputs while holding outputs steady
Explanation: Productivity is the efficient use of resources (labour, capital, personnel, land, materials, energy, information etc.) in the production of goods and services. It is also a measure of the efficiency of an industry, a person, a machine, a system and so on, in converting inputs into useful outputs. When more is accomplished (higher output) with the same amount of resources as inputs or even lesser amounts, it means we have increasing productivity. Calculating productivity is done by taking ratio of outputs produced to the inputs used in production.
Productivity = Output / Input
From this, when the denominator (input) decreases and the numerator (output) stays the same, the fraction (productivity) as a whole increases. So it can also be inferred mathematically, why this happens and therefore option D is accurate.
