Answer: Option C
Step-by-step explanation: If someone is working for himself and herself than the only hindrance on his or her freedom to operate is his or her own skills and abilities.
The local competitors are a factor of external environment, hence, they could not affect the internal operations of any person working on itself. If someone wants to operate at a high level than the existing one without having sufficient skills and resources, then there is a slight chance that he will succeed.
Hence from the above we can conclude that the correct option is C.
