Step 1: To establish the chronological order based on seniority, we require the artists' birth years.
(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: Order the artists from oldest to youngest. The correct sequence is Krishna Reddy (1925), Paramjeet Singh (1935), Anupam Sud (1944), and Kavita Nayar (1957), corresponding to the order (B), (A), (C), (D).
