Sitar, sarangi and table became popular during the _______ period.

The sitar, sarangi, and tabla emerged as prominent classical instruments during the Delhi Sultanate period (12th-16th centuries). This era saw the systematic organization of Hindustani classical music, with the development of new rhythmic cycles and melodic structures. The Mughal period later built upon these foundations, but the foundational instrumentation evolved during the Sultanate.
