Independence for Argentina

Liberation of Mexico

Removal of Napoleon Bonaparte

José de San Martín ultimately fought in South America against the Spanish for Independence for Argentina.

Answer: Option B

Explanation:

Jose de San Martin played an important role in resisting Napoleon's French armies which were advancing towards Spain, before he was asked to move into Peru. Instead of going to Peru he chose to go to Buenos Aries in 1812, which is the capital of Argentina.

The Government of Argentina were facing pressure from royal forces, thus making him go against the royal forces in Buenos Aries and support the liberation of Argentina from the royal forces.
