Answer:
Two-Party System.
Explanation:
A two-party system is a type of party system where two parties dominate political life. In the countries described by the term, other parties are also legal and active, and therefore it should not be confused with a one-party state, where parties other than the ruling party are generally illegal, but these parties do not have almost any political relevance at the national level.
