Final answer:
Sugarcane sucrose was viewed as a medicine before 1000 AD and was later grown in the Madeira and Canary Islands, leading to its widespread cultivation and the creation of plantations in the Caribbean using slave labor.
option c is correct.
Step-by-step explanation:
Before 1000 AD, sugarcane sucrose was viewed as a medicine. Arab traders introduced sugarcane to the Middle East, from where the Europeans discovered sugar during the crusades.
They initially regarded it as an exotic medicinal item. However, this perception began to change as the Portuguese and Spanish established sugarcane plantations in the Madeira and Canary Islands and people began consuming sugar as a sweetener, which led to the widespread cultivation of sugarcane in the Caribbean and other tropical areas using enslaved labor for its production.
