Correct Answer: (a) ceiling of the size of Council of Ministers
Note: The Constitution (Ninety-First Amendment) Act, 2003, restricted the size of council of ministers to 15% of legislative members with objects to strengthen Anti Defection laws. It provides the total number of Ministers, including the Prime Minister, in the Council of Ministers shall not exceed fifteen percent of the total number of members of the House of the People by inserting article 75(1A). The amendment also made same provision regarding Council of Ministers in Legislative Assembly of states under Article 164(1A). It also provided that a member of that House disqualified under paragraph 2 of the Tenth Schedule shall also be disqualified to be appointed as a Minister.
