Answer:
C) success is guaranteed as the firm implements its chosen international business-level strategy.
Step-by-step explanation:
In business, nothing guarantees success. Not even huge companies launching great products can guarantee that they will be successful, e.g. Microsoft launched a tablet (Surface) many years before Apple launched the iPad. Apple was successful, but Microsoft wasn't, and not because they lack the resources or a competitive position. China has a competitive advantage in manufacturing due to its cheap and abundant labor, and relatively easy access to productive technologies, but not every manufacturing firm in China is a success.
National competitive advantages make things "easier" but don't guarantee anything, managers must understand that if they or the employees do not work hard, do things correctly and make the right decisions, the risk of failure is always there.
