1. Correct Answer: Option C: Naval superiority
 2. Explain the logic:
     ● Option A: Government backing: While government support was significant, it was not the sole reason for British success in India. Other European powers also had government backing but did not achieve the same level of dominance.  
     ● Option B: Quality of merchandise: The British did offer quality goods, but this alone did not ensure their success. Other nations also traded high-quality merchandise.  
     ● Option C: Naval superiority: The British had a powerful navy, which allowed them to control sea routes, protect their trade interests, and establish a strong presence in India. This naval dominance was crucial in outmaneuvering competitors and securing trade advantages.  
     ● Option D: All of the above: While each factor contributed to British success, naval superiority was the most decisive element, enabling them to dominate trade and commerce in India.
