The correct answer is option 4, "Representation of Minorities." The system of proportional representation is an electoral mechanism that aims to ensure fair and proportional representation of different political parties and groups in the government. This system allocates seats in the legislature in proportion to the number of votes each party receives. As a result, it allows for a more diverse and pluralistic representation of various political ideologies and interests, including those of minority groups that may have limited electoral support. This helps to bridge the gap between majority and minority groups by giving a voice and representation to underrepresented sections of society. Therefore, proportional representation ensures that the government reflects the diversity and preferences of the entire population, rather than just the majority.
