The answer is most likely A. new producer of power tools has entered the market and is relying on low prices to attract consumers.

Explanation:

In an oligopoly, there is only a handful of companies operating in the industry and they all present similar types of goods and services (but they can differ too)

The goods and services are closedly priced in an oligopoly market. This means that the price between the goods offered by the companies in the market do not change much between the companies.

So a new manufacturerentering the market has to use a market penetration strategy and set the prices low.
