The correct answer is A) Traders provided a regular supply of guns to tribal leaders.
There was continuous political instability in West Africa between 1500 and 1700 because Traders provided a regular supply of guns to tribal leaders. During the period of the 1500s and 1700s, poor government practices corrupted people in West Africa and the smuggling of weapons and other illegal substances were allowed in the region. No authority did much because they all were part of corruption. Tribal leaders knew how to get weapons via illegal ways and traders had no consciousness in selling arms knowing that they were going to be used to create violent acts and war.
