Answer:
The correct answer is D. All of the choices are correct.
Explanation:
Count Camillo Benso of Cavour was an Italian politician who played a key role in the unification of Italy. He was elected to the parliament of the Kingdom of Sardinia in 1848 and became Prime Minister in 1852 with the support of leftists and moderate rightists. When the Crimean War broke out, he sent troops to support the great powers France and Britain. In 1858 he had a secret meeting with Napoleon III in which they agreed on French support for the annexation of the northeastern regions of Italy from Austria-Hungary in exchange for the French acquisition of the French part of Savoy and Nice. The war broke out in 1859 and Sardinia annexed Lombardy, but the French withdrew earlier than planned. He assisted Giuseppe Garibaldi in planning the Millennium Expedition, but then used the fear of Garibaldi's revolution to gain French support for the invasion of the Papal States (with the exception of Rome). When Sardinian troops arrived in southern Italy, he "gave" Victor Emmanuel II this part of the country, which led to the unification of what is now Italy.
