A - Is prepared by electrolysis of water. and
B - Industrially it is prepared from air.
1. the moisture (vapour H2O)is removed then air is liquified.
2. carbon dioxideis gets liquified. -78.5c
3. Oxygen gets liquified. -183c
4. nitrogen gets liquified. -195c
5. remaining mixture contains argon and trace of other gases.

it is prepared by the decomposition of hydrogen peroxide using a catalyst managanese 4 dioxide carried out in a stoppered flask with a delivery tube attached to collect it- in a lab.
in industry it is prepared by the fractional distillation of liquid air
