Which pair of colonial policies has most significantly contributed to the persistent underdevelopment of agriculture in Africa today?

Explanation

The colonial era saw several policies impacting African agriculture. Firstly, colonial administrations forced farmers to cultivate specific crops. Secondly, traditional land ownership systems were often altered from individual to communal forms. Thirdly, colonial powers neglected to educate and train African agricultural experts and managers. Lastly, research and development efforts were mainly focused on food production and supporting small-scale farmers and herders. Among these, the lack of training for agricultural professionals (III) combined with the focus on food production and smallholder support (IV) has most directly hindered agricultural progress, making option C the correct choice.
