Answer:
Franchises.
Step-by-step explanation:
A franchise is formed when a third party is given the right to market products using the brand name of a parent company. There is usually an agreement between the parent company and the third party on profit sharing from the franchise.
In this scenario Keith wants to try a brand recognition of a national chain, but he wants to stay in his local area and be the owner of the shop.
The best option is to form a franchise where he can use the national brand to grow his business locally.
