Solution

$A . \to (4) B . \to (3) C . \to (2) B . \to (1)$
Colour of the coordination compound is closely related to CFSE of the coordination compound. Depending upon the CFSE of given coordination compounds. Correct matching will be as follows.

$\begin{matrix} Column~I & Column~II (C o m p l e x i o n) & (C o l o u r) (A) . [C o (N H_{3})_{6}]^{3 +} & (4) . Y e l l o w i x h o r a n g e (B) . [T i (H_{2} O)_{6}]^{3 +} & (3) . P a l e b l u e (C) . [N i (H_{2} O)_{6}]^{2 +} & (2) . G r e e n (D) . [N i (H_{2} O)_{4} (e n)]^{2 +} (a q) & (1) . V i o l e t \end{matrix}$
Hence, correct choice is (b).
