Answer: d. Dynamic pricing strategy
Explanation:
The companies mentioned above are increasingly turning towards Dynamic pricing in order to maximize sales and therefore increase profitability. 
Dynamic pricing refers to a strategy where goods are priced at the optimal price based on the conditions at the time. In other words, it involves trying to sell at a price that is cheapest for the customer based on factors such as consumer willingness to pay, competition and others. 
Prices can therefore change multiple times in as little a period as a day just to ensure that customers buy the goods being offered. 
 
        
             
        
        
        
The correct answer is d). We have that government spending can also give way to products and services, just like private enterprises, thus there is no double-counting there. Services such as haircuts have their own value, which are separate from any other material products. Finally exports are also not counted twice; Raw materials though would be counted twice if we counted them for the GDP since their value is incorporated in the value of the final product. For example, we cannot count towards the GDP the value of rubber production in a country since then, if we counted the value of the tires too, we would count the value of the rubber in the tires twice (one time as rubber/ one time as part of the tire).
