The best explanation regarding the degree to which subsistence and commercial agriculture is practiced in West African countries such as Ghana and Côte d’Ivoire is Option A: "While some farmers are engaged in subsistence agriculture practices, there is significant commercial farming focused on luxury goods for export, such as coffee and cocoa."
This option accurately reflects the mix of agricultural practices in the region, highlighting both subsistence farming for local needs and commercial agriculture that targets export markets, particularly for high-value crops like coffee and cocoa, which are significant to the economies of these countries. The other options misrepresent the dominant agricultural practices and outputs in these regions.
