Answer:
The correct option is "B," which is its future productivity and future real GDP.
Step-by-step explanation:
A country that increases its saving rate will definitely have sufficient funds to invest in revenue yielding programmes and projects. An increase rate of savings will translate to more money in the hands of firms and households which will boost investment opportunities that will enhance productivity and Real GDP. Since GDP is the aggregate production of goods and services of a country within a specified period of time ( usually one year), the increased rate of savings will improve the future real GDP because of increase in investment.
