Final answer:
The growing demand for plantation labor led to an increase in slavery and the expansion of plantations.
Step-by-step explanation:
The option True is correct.
The growing demand for plantation labor did lead to an increase in slavery and the expansion of plantations. As the demand for raw materials and goods increased, particularly for crops like cotton, plantations needed a large labor force. Since the international slave trade was outlawed in 1808, planters started purchasing slaves internally from traders in a process known as the domestic slave trade. Slavery became a crucial institution in the Southern United States, with enslaved people producing a significant amount of the world's cotton.
