Who among the following is well known as an exponent of flute?

Correct answer: 3. Ronu Mazumdar is a well-known Indian classical bansuri (flute) exponent. Madhup Mudgal is a noted music personality listed by the Sangeet Natak Akademi (he is primarily known for vocal music), so he is not the flute exponent here [1]. Devabrata (Debu) Chaudhuri appears in official Padma-related listings but is not identified as a flautist in the provided sources [2]. The Shriram Shankarlal festival listing highlights prominent flautists (e.g., Hariprasad Chaurasia), illustrating the category of artists to which Ronu Mazumdar belongs. Based on established musician biographies, Ronu Mazumdar is the recognized flute exponent among the options.
