Explanation:

Parliamentary privileges are certain rights and immunities enjoyed by members of Parliament, individually and collectively, so that they can “effectively discharge their functions”. When any of these rights and immunities are disregarded, the offence is called a breach of privilege and is punishable under law of Parliament.

• A notice is moved in the form of a motion by any member of either House against those being held guilty of breach of privilege.
• A member may, with the consent of the Speaker or the Chairperson, raise a question involving a breach of privilege either of a member or of the House or of a committee thereof. The rules however mandate that any notice should be relating to an incident of recent occurrence and should need the intervention of the House.
• The Speaker/RS chairperson is the first level of scrutiny of a privilege motion. The Speaker/Chair can decide on the privilege motion himself or herself or refer it to the privileges committee of Parliament.

Hence both statements 2&3 are correct.
