Public opinion allows an organised government to

Public opinion serves as a vital feedback mechanism in governance. It allows an organised government to find out what the public thinks of its activities. Through public opinion, the government gauges citizens' reactions to its policies, programmes, and decisions, enabling it to adjust or continue its course of action accordingly.

Governments monitor public opinion through various channels, including the press, opinion polls, public hearings, social media, petitions, and elections. This information helps democratic governments remain responsive and accountable to the people they serve.

The other options describe negative actions that go against the purpose of public opinion in a democratic system. Infringing on the rights of opponents, manipulating governmental processes, and oppressing citizens are abuses of power, not legitimate uses of public opinion. In fact, public opinion serves as a check against such abuses by allowing citizens to express their dissatisfaction and hold the government accountable.
