During a company interview, what did the chief executive officer deny?

The chief executive officer's denial of the company being involved in merger talks is significant because such information can have a substantial impact on the company's stock value and investor relations. When a CEO addresses merger discussions, they often aim to manage public perception and maintain investor confidence. By stating that the company is not in merger talks, the CEO is likely trying to quell any speculation that could lead to uncertainty among shareholders or analysts.

In contrast, the other options involve issues that could be either common knowledge or determine the operational stability of the company, which might not require a denial in the same way. Financial difficulties, employee layoffs, or expansion plans typically reflect on the company's operational status or strategy without necessarily having the same implications as a potential merger, which usually involves greater scrutiny and expectation from stakeholders.
