Answer:
c) Rick has an external locus of control.
Step-by-step explanation:
What can challenge Rick in his quest to become a successful entrepreneur is that he has an external locus of control, which occurs when an individual relates events related to their failures or successes to external variables that are not their responsibility, such as fate, luck or bad luck.
The external locus of control can pose a challenge for Rick in the sense that an entrepreneur's success is related to his own personal control and personal efforts to make the business viable and successful in the market. It is necessary for the entrepreneur to understand that there are risks inherent to the business and that a business can work according to their efforts, learning and planning, that is, the entrepreneur and their control and management actions will be responsible for the success or failure of the business, and not just external factors like fate or bad luck.
