Answer:
D) Five Guys Burgers
Step-by-step explanation:
Five Guys Burgers is the fastest growing fast food chain in the US, although that can be explained due to its relatively small size compared to other huge chains like McDonald's, Burger King or Wendy's. It currently operates 1,500 restaurants around the world (most in the US) and plans to open 1,500 more in the next few years.
Its greatest advantage is that is offers a differentiated service and its relative small size allows it to be more flexible. Its website also gets a lot of online traffic.
The combination of all these factors means that they have a lot of potential to grow and gain a higher market share.
