Buying slaves from local African chieftains indicates what?

Slave trade was a multi-layered trade chain

Buying enslaved people from local African chieftains indicates that the slave trade operated through a multi-layered commercial chain, making option A correct. European traders were not usually obtaining captives through one simple, direct transaction from the places where people were seized. Local authorities, brokers, merchants, coastal traders, shipowners and plantation buyers could all form links in the wider system. This does not make local leaders or European traders equally responsible in every situation, but it shows that the trade involved multiple participants and stages. Option C is the direct opposite of the evidence. Options B and D are incorrect because slavery was an economic and political system of forced human trafficking, not merely a parliamentary law or educational arrangement.
