Solution

The correct option is C
A turbid solution is formed.

When calcium nitrate reacts with sodium hydroxide, a white precipitate of calcium hydroxide is formed, but with ammonium hydroxide, no precipitate is formed. This is because ammonium hydroxide being a weak base do not furnish enough $O H^{-}$ ions to cause precipitation.

$C a (N O_{3})_{2} + 2 N a O H \to C a (O H)_{2} (↓) + 2 N a N O_{3}$
