Answer:
The correct answer is B. Cotton cloth.
Step-by-step explanation:
From 1780 to the beginning of the 19th century, British exports of cotton fabrics increased tenfold. At the same time, productivity increases allowed to reduce the prices of some products to one sixth. Similar transformations in the short term of two or three decades had never occurred before. There is no doubt that in the face of such magnitude it is not an exaggeration to call it a revolutionary; this leap forward that gave birth to modern economic development is one of the fundamental milestones of England's economic history.
At the level of international trade, the transformation of the British cotton industry made it possible for English merchants to dominate the world market in a way and on a scale that had never occurred.
