Identify the country having a dual party system.

USA

*The correct answer is Option 3 - USA*

The USA is a classic example of a country with a dual party system. The two dominant parties in the US are the Democratic Party and the Republican Party. These two parties have held power for over a century, and it's rare for a third party to gain significant influence.

Other options:

China: China operates under a one-party system, with the Communist Party of China holding absolute power.
Cuba: Cuba also has a one-party system, dominated by the Communist Party of Cuba.
Myanmar: Myanmar has a multi-party system, but the military junta still holds significant power and influence.
