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.
