Solution

The correct option is A $M g (N H_{4}) P O_{4}$
A white precipitate of magnesium ammonium phosphate is formed when $M g S O_{4}$ reacts with $N H_{4} O H$ and $N a_{2} H P O_{4}$ .
$M g S O_{4} + N a_{2} H P O_{4} + N H_{4} O H \to M g (N H_{4}) P O_{4} White ppt. ↓ + N a_{2} S O_{4} + H_{2} O$
