The correct answer is - C. encouraging other countries to use England's technology.
England was the country that developed the industry. It managed to produce new technology that led to a large scale, quick, cheaper, and quality manufactured goods, that technology were the machines. After the machines were constructed lot of factories were opened across the country, the economic growth was incredibly high, and the country got huge amounts of wealth.
England also though that in order for the industrialization to reach its full potential and the industry to continue to grow it had to spread around its technology. And so it happened, with England encouraging the other European countries to use its technology and industrialize, resulting in economic boom across Western Europe, and later in the United States as well.
