The correct answer is India, as that territory was considered the "jewel in the crown" of the British Empire.
From 1770 to 1947, India was part of the British Empire and was its most important colony. They called it the jewel of the Crown because of its size and wealth, with its almost 5,000,000 km2 and 300,000,000 inhabitants, and its supply of cotton, jute, wheat, oil, tea and minerals, which were provided at a very low cost to Great Britain.
