With regard to a Constitution Amendment Bill, which one of the following statements is not correct?

According to Article 368, a Constitution Amendment Bill must be passed in each House of Parliament separately by a special majority, which consists of a majority of the total membership of the House and a majority of not less than two-thirds of the members present and voting [2]. Unlike ordinary legislation, the provision for a joint sitting under Article 108 is not available for resolving deadlocks between the Lok Sabha and Rajya Sabha regarding a Constitution Amendment Bill [4]. Therefore, the Speaker cannot call a joint sitting for this purpose. Such bills can be introduced in either House of Parliament [3]. Furthermore, they can be sponsored by either a Minister (Government Bill) or a private member [2]. Since statement 1 incorrectly suggests that a joint sitting can be called, it is the incorrect statement.
