Which of the following countries are well known as the two largest cocoa producers in the world?

The correct option is Côte d’Ivoire and Ghana.

To understand why this is the correct answer, we can look at the global distribution of cocoa production:
1. Côte d’Ivoire (Ivory Coast): Located in West Africa, Côte d’Ivoire is consistently the single largest producer of cocoa beans globally, supplying roughly 40% of the world's total crop.
2. Ghana: Also located in West Africa and neighboring Côte d’Ivoire, Ghana is the second-largest producer of cocoa beans in the world, accounting for around 15% to 20% of global production.
3. Combined Production: Together, these two West African nations account for approximately 60% of the world's total annual cocoa production, making them the two most dominant cocoa-producing countries by a significant margin.

Looking at the other options:
- Algeria and Morocco are located in North Africa, where the dry climate is not suitable for growing cacao trees.
- Botswana and Namibia are located in Southern Africa, largely featuring arid and semi-arid conditions unsuitable for cocoa cultivation.
- Madagascar and Mozambique do produce some agricultural exports, and Madagascar produces high-quality specialty cocoa, but their volumes are extremely small compared to the global leaders.

Therefore, Côte d’Ivoire and Ghana are well known as the two largest cocoa producers in the world.
