Answer:
The correct answer is letter "C": getting alliance partners to reach decisions fast enough to stay abreast of rapid advances.
Step-by-step explanation:
There might be many different factors that complicate international business relationships. Dealing with different cultures, trading policies and language barriers are examples of those barriers. However, alliances can be established as well so the company's decisions can be decentralized. In that way, the firm can move according to the market flow.
Thus, option "C" is not a hazard or difficulty related to international alliances.
