A production possibility frontier is a curve or graph that shows the various amounts of any two products which can be produced when both the products depends on same finite source.
In the context, a society produces two products namely, beer and donuts. As the production possibility frontier moves up, producing more donuts by the society increases the opportunity cost for producing beer as the society produces both donuts as well as beer.
Hence the correct option is (C).

<u>Problems faced in India(water and air pollution)</u>
<em>A diverse range of pollution sources co-exists in urban environments. Conventional sources of air pollution include vehicular emissions, coal-based power plants, fossil fuel consumption in industries and some agricultural activities such as fertilizer application and farm fires. Air pollutants can be natural or may be the result of various anthropogenic activities. Examples include production of brick kilns that use raw wood, agricultural waste or poor quality coal used as a fuel, the roadside burning of organic and plastic waste, cooking that involves the burning of solid biomass or cow dung and the unintentional burning of municipal solid waste at landfills, and construction activities (Kumar et al, 2015) (Figure 3). The local emission inventories point to about 5300 and 7550 tons yr−1 of PM10 and PM2.5 release from waste burning in Delhi, respectively, while the corresponding emissions from construction are 3250 and 10,750 tons yr−1 (Guttikunda and Goel, 2013). Other such sources include diesel generators for temporary power generation in cities, traffic congestion, and </em>
<u>Problems faced in China(water and air pollution)</u>
For over a decade in China, China has been the world’s largest annual emitter of greenhouse gases. Regardless of some pro-ecological alternatives and investments in alternative energy sources, the country’s emissions keep growing, contrary to the worldwide trends.
That seems to be the most worrying part. The other main global polluters, for instance, the US, have been successfully pursuing the reduction of greenhouse gas and particulate matter emissions. That’s not the case with China, which continues to fulfill its growing demand for energy with fossil fuels.
