Which one of the following countries has more or less evolved a two-party system?

1. A two-party system is a political system where two major political parties consistently dominate the political landscape. 2. Sri Lanka has historically had a multi-party system, although often dominated by coalitions led by major parties. 3. Bangladesh also operates under a multi-party system, characterized by intense rivalry between two main parties/alliances but not strictly a two-party system evolution. 4. Pakistan has a multi-party system with periods of military rule and shifting political alliances. 5. Myanmar (Burma) has experienced long periods of military rule and is transitioning, but its political system has not evolved into a stable two-party system. Historically, some might argue Bangladesh leaned towards a de facto two-party dominance between Awami League and BNP more than the others listed, but none perfectly fit the description of an *evolved* two-party system like the US or UK. However, compared to the others, Bangladesh's political dynamics often revolved around two major poles.
