Which of the following types of political party systems usually develops with a voting system of single-member districts?

A two-party system typically develops in a voting environment that utilizes single-member districts because of how votes are translated into representation. In a single-member district system, each electoral district elects one representative. This often leads to a scenario where only two main parties dominate the political landscape because voters tend to gravitate toward those parties that have the highest chances of winning.

The winner-takes-all nature of single-member districts discourages smaller parties from gaining footholds, as they frequently receive insufficient votes to win seats in the legislature. This results in a consolidation of political power into two major parties that appeal to a broader range of voters in order to maximize their electoral success. Hence, the structure of a two-party system emerges more naturally from single-member district arrangements compared to other systems that may include multiple representatives or parties.
