Answer: Arabs, Sugarcane
Step-by-step explanation:
Question is not ordered properly but based on the options, the above is the correct answer.
The Arabians are the occupants of Southwest Asia and indeed in the medieval world, they supplied the rest of Europe with sugar using techniques that they imported from Indian farmers.
The sugar was extracted from Sugarcane and the Arabs built large plantations to have access to it. They artificially irrigated the crops as they require more of a tropical climate with lots of rain.
