Step-by-step explanation:
The starting point for most companies when considering market expansion strategies is typically Market penetration and market diversification (Option D). This approach entails a company focusing on selling its existing products or services into its existing markets to gain a higher market share. This is a common initial strategy before moving on to more complex strategies like country diversification or market concentration.
With globalization playing a critical role, companies can contribute to economic growth by targeting market penetration to ensure products reach areas of the world that are in need, supporting the global economy's balance and stability. After establishing a strong domestic presence or in markets similar to the home market, businesses often move towards market diversification, introducing their products or services to new markets to continue their growth and reduce dependence on a single market.
