Answer:
B) Demand decreases and becomes more elastic.
Step-by-step explanation:
In this example, we are talking about firms that compete in a monopolistically competitive market. A monopoly is a market structure that occurs when a company is the only supplier of a good. Under the situation described, the change a firm would experience is that demand decreases and becomes more elastic. The elasticity of demand refers to how responsive demand is to a change in another economic factor.
