A) Smaller companies then have to try a lot harder and install their own wires.
B) Because deregulation has led to fewer enormous firms with far less regulation.
C) Because without competition, companies have no reason to try hard to deliver a good product.
D) Monopolies lead to corruption, which inevitably leads to harmful effects for society.
