The Ramayana in Sanskrit was composed by the sage Valmiki. The correct spelling is 'Valmiki,' not 'Rishi Balmiki.' Note that options A and B contain spelling errors - 'Kalidash' should be Kalidasa and 'BedBaysh' is likely a corruption of Vidyapati (Bengali poet who translated Ramayana, not the original Sanskrit composer). Kritibash Ojha wrote a Bengali version, not the Sanskrit original.
