Answer:
B) threat of new entrants is most likely low.
Step-by-step explanation:
We could classify the telecom industry in Andalus (or any other country) as an oligopoly, where only a handful of firms control the entire market. As any oligopoly, the threat of new entrants is relatively low because of the high investment required and economies of scale achieved by existing firms.
Also, the bargaining power of suppliers is extremely large, and disproportionate compared to the buying power of customers. Only steep competition among telecom companies levels the field. That is why governments generally regulate telecom markets. for example, in some places the user is the owner of the phone number, so they do not have to be stuck with a company just to keep their old number.
