I know this is really late, but I'm posting this for the other Plato users as well because I come upon answers like these and it frustrates me so much we just want the answers but people like the other person that commented only our waste time. The answer is going to be D. to fairly allocate native slaves to the Spanish settlers. I've had to retake this test multiple times due to situations like this or people putting the wrong answers. I know for a fact it's D. I've done research on all my answer without using Brainly. (I'm not saying everyone's answers are like this I'm just saying some peoples are.) Good luck guys. :S
