Explanation:

All the statements are correct.

• Any Member of Parliament who is not a minister is referred to as a private member.
• Its drafting is the responsibility of the member concerned. Its introduction in the House requires one month’s notice.
• The government bills\public bills can be introduced and discussed on any day, private member’s bills can be introduced and discussed only on Fridays.
• In case of multiple Bills, a ballot system is used to decide the sequence of bills for introduction.
• The Parliamentary Committee on Private Member's Bills and Resolutions goes through all such Bills and classifies them based on their urgency and importance.
• Its rejection by the House has no implication on the parliamentary confidence in the government or its resignation.
• Upon conclusion of the discussion, the member piloting the bill can either withdraw it on the request of the minister concerned, or he may choose to press ahead with its passage.

Hence option 4th is correct.
