How many companies have a fortune rank and have a headquarters in Delaware?

The correct answer, which indicates that there are 175 companies with a Fortune rank that have their headquarters in Delaware, reflects data that establishes Delaware's prominence as a business hub. Many Fortune-ranked companies choose to incorporate in Delaware due to its favorable corporate laws, well-established legal precedents, and business-friendly environment. This ranking shows the significant number of influential firms that have chosen to make Delaware their home, enhancing the state's reputation in the corporate world.

This figure demonstrates not only the attractiveness of Delaware for incorporation but also the trend of established companies recognizing the advantages that come with being headquartered there. The question highlights a specific intersection of location and business stature, emphasizing Delaware's importance in the corporate landscape. Other options do not align with this understanding as they suggest a different, non-factual count that does not accurately reflect the known data.
