Answer:
4) The company is likely to be very profitable as long as the threat to entry is low
Explanation:
This is a type of imperfect competition, it is not an oligopoly because the power of suppliers is low, but it is not a monopolistic competition either because the threat of new substitutes a is also low (high barriers of entry).
But given the circumstances, I would guess that as long as only a few suppliers exist, they will be able to charge a very high price for their product resulting in high profits. Satellites are not very common products and only a few companies in the world are able to produce them due to technological constraints. They are also very expensive (they cost millions of $), and that reduces the number of potential clients to only a small number of governments and few corporations.
A balance exists between a small supply and a small demand, with a very high equilibrium price.
