Which of the following is a way that MPs can raise concerns in Parliament?

Introducing a private members' bill is an established method for Members of Parliament (MPs) to raise concerns in Parliament. This process allows MPs, who are not part of the government, to propose legislation or discuss issues they believe need attention. Private members' bills can address various topics, enabling MPs to highlight specific concerns of their constituents or issues they are passionate about.

This option provides a formal channel through which MPs can advocate for change or bring attention to matters that may not be prioritized by the government. It encourages democratic engagement and allows for debate on important issues within a structured parliamentary framework.
