The correct answer is C) suitable climate and soil.
What ensured the success of tobacco cultivation in the southern colonies was a suitable climate and soil.
Tobacco was the king of cash crops in Virginia. It was very successful that it was exported to Europe. It was John Rolfe that brought the first seeds to Virginia. Some historians say that he brought them for the Trinidad Island in the Caribbean. Those seeds and the fertile land of Virginia produced better tobacco leaves; more grey and bitter. That was the secret of its taste.
