Solution

The correct option is D $N a O H$ solution
$F e (O H)_{3}$ can be separated from $A l (O H)_{3}$ by addition of NaOH solution.
Only $A l (O H)_{3}$ is soluble in excess of NaOH followed by boiling to form sodium meta-aluminate while $F e (O H)_{3}$ is insoluble.
$A l (O H)_{3} + N a O H \to N a [A l O_{2}] + 2 H_{2} O$
