The correct Answer is:

NaOH ishighly deliquescent as it has the property ofpicking up moisture from the air to such an extent as to dissolve in it, becoming liquid on exposure to air. Hygroscopic-has a tendency to absorb moisture. Eflorescence is the property of some crystalline salts of losing a part of their water of crystallization and becoming powdery on the surface.
