Of all the European nations who came as traders to India after new sea routes were discovered, England emerged as the most powerful and successful by the end of the eighteenth century. The major factors which can be attributed to the success of the English against other European powers- Portugal, the Netherlands, France and Denmark-in the world in general and in India, in particular, were as follows:
Structure and Nature of the Trading Companies: The English East India Company, formed through the amalgamation of several rival companies at home, was controlled by a board of directors whose members were elected annually. The shareholders of the company exercised considerable influence, as the votes could be bought and sold through the purchase of shares. The trading companies of France and Portugal were largely owned by the State and their nature was in many ways feudalistic. Hence option 1 is not correct.
Naval Superiority: The Royal Navy of Britain was not only the largest; it was the most advanced of its times. The victory against the Spanish Armada and against the French at Trafalgar had put the Royal Navy at the peak of the European naval forces. In India too, the British were able to defeat the Portuguese and the French due to the strong and fast movement of the naval ships. The English learned from the Portuguese the importance of an efficient navy and improved their own fleet technologically. Hence option 2 is correct.
Industrial Revolution: The Industrial Revolution started in England in the early 18th century, with the invention of new machines like the spinning Jenny, steam engine, the power loom and several others. These machines greatly improved productivity in the fields of textiles, metallurgy, steam power, and agriculture. The industrial revolution reached other European nations late and this helped England to maintain its hegemony. Hence option 3 is correct.  
Use of Debt Market: One of the major and innovative reasons why Britain succeeded between the mideighteenth century and the mid-nineteenth century, while other European nations fell, was that it used the debt markets to fund its wars. The world‘s first central bank-the Bank of England-was established to sell government debt to the money markets on the promise of a decent return on Britain‘s defeating rival countries like France and Spain.
Britain was thus enabled to spend much more on its military than its rivals. Britain‘s rival France could not match the expenditure of the English; between 1694 and 1812, first under the monarchs, then under the revolutionary governments, and finally under Napoleon Bonaparte, France simply went bankrupt with its outdated ways of raising money. Hence option 4 is correct.
