With reference to Mian Tansen, which one of the following statements is not correct?

Statement (a) is the correct answer because it is factually incorrect; the title 'Tansen' was conferred upon him by Raja Vikramjit of Gwalior (or Raja Ramchandra of Rewa), whereas Emperor Akbar gave him the title 'Mian'. Option (d) is a common distractor but is a true statement, as Tansen is credited with inventing several famous Ragas such as Mian ki Malhar and Darbari Kanada. The core concept being tested is the cultural history of the Mughal era and the specific biographical details of the 'Navratnas' in Akbar’s court.
