b) They debate and decide policies.
Political leaders are responsible for leading their countries or organizations and making decisions that affect their citizens or members. They are typically elected or appointed to their positions, and they have the authority to make policies that reflect the needs and interests of their constituents. While they may seek advice from officials and experts, ultimately it is the political leaders who debate and decide policies. It is also common for political leaders to leave their positions after a certain period, as opposed to staying in their positions for their whole careers.
