Solution

The correct option is A

X = NaOH, Y = H2O and Z is washing soda


Washing soda (chemical name: sodium carbonate) can be used as a cleaning agent for domestic purposes. In the laundry room, the high alkalinity of washing soda allows it to act as a solvent in removing a wide range of stains. For home laundry, washing soda can be dissolved in water to create a presoaking solution for tough stains like grease, blood, tea and coffee stains.
