Final answer:
Harmon Dobson's business partner when he first opened Whataburger was Paul Burton. They had differing visions for the company's growth which led to Dobson taking full control after buying out Burton's shares. The correct option is A.
Step-by-step explanation:
Harmon Dobson's business partner when he first opened Whataburger was Paul Burton. Whataburger was founded in 1950 in Corpus Christi, Texas, and it was the collaboration between Harmon Dobson and Paul Burton that launched the now famous burger chain. Their partnership, however, did not last long, as they had different visions for the company's expansion.
Harmon Dobson aimed for a bold strategy of rapid growth, while Paul Burton was more cautious. This led to a split, with Dobson buying Burton's shares and taking full control of the company. Under Dobson's leadership, Whataburger continued to expand and eventually became a popular fast-food chain with a significant presence across the southern United States.
Hence, Option A is correct.
