Solution

The correct option is C $C l_{2}, N a O H$ solution (cold, dilute)
The reactions are as follows:
(a) $2 F_{2} + 4 N a O H \to 4 N a F + 2 H_{2} O + O_{2}$
(b)
$2 F_{2} + 2 H_{2} O \to 4 H F + O_{2}$
(c) $C l_{2} + 2 N a O H \to N a C l + N a C l O + H_{2} O$
(d) $2 C a O C l_{2} + H_{2} S O_{4} \to C a C l_{2} + C a S O_{4} + 2 H C l + O_{2}]$
Hence, the correct answer is option (c).
