The concept of zero as both a number and a placeholder was invented in ancient India. Indian mathematician Brahmagupta (7th century CE) was the first to formalize rules for operations involving zero, including addition, subtraction, and multiplication. The concept later spread to the Islamic world and then to Europe through the work of scholars like Al-Khwarizmi.

The Crimean War (1853-1856) was fought between Russia and an alliance of Western European powers including Britain, France, and the Ottoman Empire. The Gulf War occurred in 1990-91, the Crusades were medieval religious wars (11th-13th centuries), and the 100 Years' War was between England and France in the 14th-15th centuries.

In 1990-1991, a US-led coalition of 34 countries fought against Iraq in the Gulf War to liberate Kuwait after Iraq's invasion. The Peninsula War (1808-1814) was in Spain, and the Vietnam War (1955-1975) was in Southeast Asia.

The Vietnam War (1955-1975) is widely considered America's worst military defeat and is also known as the Second Indochina War. The Korean War ended in stalemate, Pearl Harbour was an attack not a war, and the Gulf War was a US victory.

The Crusades (1095-1291) were religious wars spanning approximately 200 years, though related conflicts extended this period. They involved massive casualties across multiple campaigns. While '300 years' is an approximation, the Crusades is the best answer among the options. The Cold War (44 years), Hundred Years' War (116 years), and American Revolution (8 years) don't match the scale or duration described.

The Great Game (19th century) was the geopolitical rivalry between the British and Russian empires over Central Asian territories. The Durand Line (1893) demarcating the Afghanistan-Pakistan border was indeed a resolution of tensions between these powers in this region. The other options don't fit: Persian War involved Greece-Persia, Indo-Russian War is not a historical term for this context, and Afghanistan War is too generic.

The Russo-Japanese War (1904-1905) was fought over control of Port Arthur (now Lüshunkou), a strategic warm-water port on the Liaodong Peninsula. The war began with a Japanese surprise attack and ended with the Treaty of Portsmouth. The other options don't match: Sino-Japanese wars involved different conflicts (1894-95, 1937-45), and the Opium Wars (1839-42, 1856-60) were between China and Britain.

The Opium Wars (1839-1842 and 1856-1860) were fought between the Qing Dynasty of China and the British Empire in the mid-19th century. They were triggered by trade disputes and opium trafficking. The other options are incorrect: Mongolian and Tibetan Wars don't fit the description, and the Sino-Japanese Wars occurred later (1894-95, 1937-45).

The Second Battle of Panipat (1556) was fought during Akbar's reign (though he was represented by his regent Bairam Khan). It resulted in a decisive Mughal victory over Hemu. The First Battle (1526) established Mughal rule under Babar, and the Third Battle (1761) was fought much later between Afghans and Marathas.
