b. huge populations of africans were redistributed throughout europe.
c. european governments became unable to financially support their colonies.
d. entire african societies were destroyed in conflicts with slaves traders.

The long term cost of the Atlantic Slave was that entire societies in Africa were destroyed - the correct answer is D.

Most of the slaves were bought from the local slave traders, and the money paid to them was an incentive to capture slaves. This means that while the slaves were taken mostly from the coast, the conflicts that rose from the slave capture extended deep into the land

Their solution was to tax the colonists.
