Explanation:

Over the last few sessions, MPs mainly from the Opposition have often alleged their questions have been disallowed in Parliament of India.

• In both Houses, elected members enjoy the right to seek information from various ministries and departments in the form of starred questions, unstarred questions, short notice questions and questions to private members.
• Usually, MPs’ questions form a long list, which then go through a rigorous process of clearance. The admissibility of questions in Rajya Sabha is governed by Rules 47-50 of the Rules of Procedure and Conduct of Business in the Council of States.
• Once a question that fulfils the conditions of admissibility is received, the Secretariat sends it to the ministry concerned.
• Once the facts are received from the ministry, the question is further examined for admissibility.
• A final list of questions is circulated to ministers, on the basis of which they frame their answers.

What are starred, unstarred and other categories of questions?

• STARRED QUESTION: The member desires an oral answer from the minister. Such a question is distinguished by the MP with an asterisk. The answer can also be followed by supplementary questions from members.
• UNSTARRED QUESTION: The MP seeks a written answer, which is deemed to be laid on the table of the House by the concerned minister.
• SHORT NOTICE QUESTION: These are on an urgent matter of public importance, and an oral answer is sought. A notice of less than 10 days is prescribed as the minimum period for asking such a question.
• QUESTION TO PRIVATE MEMBER: A question can be addressed to a private member under Rule 40 of Lok Sabha’s Rules of Procedure, or under Rule 48 of Rajya Sabha’s Rules, provided that the question deals with a subject relating to some Bill, resolution or other matter for which that member is responsible.

Hence only statement 1st is correct.
