Option B is right that the to encourage people to settle in the colonies was the purpose of the Headright system.
Began in 1618 at Jamestown in Virginia, the Headright system was a method of granting the land legally. This system was created to attract immigrants and it was an attempt to solve scarcity of labor in Virginia, caused by the appearance of the tobacco economy. The Headrights were awarded to anyone who would agree to pay the shipping costs of the labor or slave. accordingly, colonists who were living in Virginia were given with two Headrights, and the migrated Colonists were awarded one Headright and the individuals received one Headright every time they paid for the journey of another individual. Plantation owners benefited from the Headright system when they met for the transportation of imported slaves. The increasing money amount required to bring bound slaves to the colonies and this contributed to the shift towards slavery in the colonies.
As a muslim, I can positively say that Islam does have the pre-Islamic Arabian influences, such as loose clothing to prevent the body's curves from showing, not consuming alcohol or eating pork of obtaining animal's blood. However, there are practices that are different. Such as believing in one God, not worshipping any idol, object, or person. Believing God have no children or a wife, neither does he have any family. He is one and only, no one is like him. Not talking to a non-marram, or someone who's not your close family such as cousins, uncles, aunts, husband , or wife. Not taking intrest, since that's not your own earned money. Also praying five times a day and fasting in Ramadan. P,u'd giving as much charity as possible. If you have any other questions, feel free to ask.
