Option 1: "1878: Second Anglo-Afghan War" is indeed correctly matched. The Second Anglo-Afghan War began in November 1878 when Great Britain, fearing what it saw as Russian expansionism in the region, invaded Afghanistan from India, which was then a British colony.

Option 2: "1885: Ilbert Bill Controversy" is not accurate. The Ilbert Bill Controversy took place in 1883, not 1885. The controversy arose because of the Ilbert Bill, which proposed giving Indian judges the right to try British offenders in India.

Option 3: "1785: Fox`s India Bill" is incorrect. Fox`s India Bill was introduced to the British Parliament in 1783, not in 1785. It was proposed by Charles James Fox and sought to reform the methods of governing British India.

Option 4: "1898: Lord Curzon becomes the Viceroy" is not right. Lord Curzon became the Viceroy of India in 1899, not in 1898. He was a controversial figure whose policies still affect India to this day.

Therefore, the correct answer is option 1: 1878: Second Anglo-Afghan War.
