Which of the following pairs of musicians and their instruments is INCORRECT?

K Vaidyanathan - Sitar

The correct answer is Option (1) - K Vaidyanathan - Sitar

K. Vaidyanathan: According to reliable sources, Kunnakudi Vaidyanathan was a renowned violinist, not a sitar player.

Others: Pt. Ram Narayan is known for Sarangi, Ustad Vilayat Khan for Sitar, and Bismillah Khan for Shehnai. These pairings are correct.

Therefore, K. Vaidyanathan being associated with Sitar is the incorrect pair.
