Which group of immigrants did southern planters often prefer to use for very dangerous jobs because slaves were too expensive to put at risk?

Africans

Explanation:

When it became obvious that to acquire indentured servants is expensive, the southern planters initially turned to Native Americans for labor. However, they later realized that they were vulnerable to European diseases and died too often. This led the southern planters to turn to slaves from Africa to work for them. This is evident in the report that before 1665, there were less than 500 Africans in Virginia, but by 1750, more than 40 percent made the total of the southern population of which most if not all are enslaved to work on the plantation.
