Correct answer: A→R,S; B→Q,S; C→P,Q; D→P,R. Radial nodes = n - l - 1; Angular nodes = l. (A) 2s (n=2, l=0): Radial nodes = 1 (R); Angular nodes = 0 (S). A matches R,S. (B) 1s (n=1, l=0): Radial nodes = 0 (Q); Angular nodes = 0 (S). B matches Q,S. (C) 2p (n=2, l=1): Radial nodes = 0 (Q); Angular nodes = 1 (P). C matches P,Q. (D) 3p (n=3, l=1): Radial nodes = 1 (R); Angular nodes = 1 (P). D matches P,R.
