From 1500 to 1880 ce, how many slaves were estimated to be forcibly moved from africa to the america’s and what percent were estimated to have died from the journey?

The amount of slaves that were estimated to be forcibly moved from africa to America would be: around 10-12 Million slaves,
And from that number, around 15% of them have been estimated to died from the journey.
During the voyage, the slaves were forced to rows the boat while being tortured and not given enough nutrition, which caused a massive number of death during the transportation process.

Ibelieve the answer is (a) true.
