Step 1: To determine the chronological sequence by seniority, we need to know the birth years of the artists.
(B) Krishna Reddy: Born in 1925
(A) Paramjeet Singh: Born in 1935
(C) Anupam Sud: Born in 1944
(D) Kavita Nayar: Born in 1957
Step 2: Arrange the artists from earliest birth year to latest. The correct order is Krishna Reddy (1925), then Paramjeet Singh (1935), then Anupam Sud (1944), and finally Kavita Nayar (1957). This corresponds to the sequence (B), (A), (C), (D).
