It is a pathway, which can resolve issues or evaluate quickly and efficiently would be a conceptual workaround. These rules of thumbs strategies reduce the time for decision-making, which enables employees to work without constantly reflecting on their next step. This approach uses shortcuts to deliver accurate methods throughout the sense of limited time or deadline, and wrong choices can be defined as follows:

 - In choice b, It is used in problem-solving, that's why it is wrong.
 - In choice d, It is based on statistics, that's why it is incorrect.   
 
 
        
             
        
        
        
Answer:
Market movements and price fluctuations are influenced by a number of factors, such as economic reports, large institutional block trades and such like. Of all these factors, one that is often underestimated is the impact of commodity prices. Fluctuating commodity prices not only have a significant impact on business, they also impact the trading markets and the overall economy. Generally, the impact of commodity price fluctuations depends on whether that economy is a net importer or net exporter of commodities.
For economies that are net importers, commodity price increases act almost like trade tariffs. This is because it makes the import of raw materials and sources of energy, required for the everyday functioning of different economic sectors, more expensive.
Economies that are net exporters, on the other hand, benefit from increasing prices, since their income increases with the sale of those commodities. At the same time, a steep rise in prices could reduce the demand for commodities and lead to losses.
