Answer:
The integration or growth of a company can occur horizontally or vertically, depending on whether it acquires competing companies that develop their business in parallel (horizontal integration), or it acquires companies or businesses that are in a different stage of the production process (companies that generate raw materials, transport, marketing, etc.).
Thus, if Electrolux expands its business by acquiring a competitor such as Whirlpool, it will be a case of horizontal integration. In contrast, if Electrolux acquires a company dedicated to the marketing of products, such as Best Buy, it will be a case of vertical integration.
