Answer:
c. a sole proprietorship because Cal is a sole proprietor.
Explanation:
Cal sells "DownSize," a weight-reduction program, from a Web site, in competition with Eat-Less Inc.'s product "Fit 'n Trim." Eat-Less files a suit against Cal, alleging in part that he is a sole proprietor, but his enterprise should be deemed a different form of business. Cal's enterprise should most likely be considered a corporation because Cal is a sole proprietor and his enterprise is likely to be considered as sole proprietorship.
