First of all, a definition of productivity is required: it is the efficiency with which a country organizes labor and capital in order to produce more with the same amount of workers. Increased productivity, according to mainstream economic doctrine increases economic growth, therefore the answer would be a. increasing economic growth. However, the issue is way more complex, If an increase of productivity is the result of exploitative practices, which are not only immoral but inefficient, the economic growth will be higher but unstable as exploited workers will rebel and go on strike and even if the strikes are suppressed by the police or employers, such economic growth will only continue in the short term since it will deplete both human and natural resources and will only benefit a tiny minority of the population.
