The correct answer is - A) environmental changes decreased the production of food.
During its existence, Rome, did not faced any major challenges from environmental aspect that would reduce the food supplies to a point where it will make a big problem in the country. In times when there were some minor food problems, Rome was just using the food produced in the territories it had under its control, so it was never a major problem during its existence.
The British conquered Myanmar, and the French conquered Laos, Cambodia, and Vietnam in the the 1800's and 1900's, and the conquerors always leave some of their culture behind. Hope this helps. Good luck!
