Solution

The correct option is A $K_{3} [C u (C N)_{4}]$
Option (B) is correct.
$C u S O_{4}$ when reacts $K C N$ forms $C u C N$ ,which is insoluble in water.

$C u C N$ is soluble in excess of $K C N$ , due to formation of $K_{3} [C u (C N)_{4}]$ .
$C u S O_{4}$ when reacts $K C N$ forms a white precipitate of cuprous cyanide and cyanogen gas. The cuprous cyanide dissolves in excess of $K C N$ , due to formation of $K_{3} [C u (C N)_{4}]$ .

$C u S O_{4}$ + $2 K C N$ $\to$ $C u (C N)_{2}$ + $K_{2} S O_{4}$

2 $C u (C N)_{2}$ $\to$ $2 C u C N$ + $C N - C N$

$C u C N$ + $3 K C N$ $\to$ $K_{3} [C u (C N)_{4}]$
