The crystals of washing soda undergo efflorescence because it is hydrated salt containing 10 molecules of water of crystallization. When the crystals of washing soda exposed to air loose water of crystallization and form white powder of sodium carbonate monohydrates.Na 2CO3 .

Efflorescence is the process where a hydrated salt loses its water of crystallization when exposed to dry air, turning into a white powder.

Sodium carbonate crystals (Na₂CO₃·10H₂O), also known as washing soda, undergo this process by losing water and forming a white powdery residue

The answer is D. Efflorescence
