If two soap bubbles of different radii are connected by a tube, then

A

Air flows from bigger bubble to the smaller bubble till sizes become equal

B

Air flows from bigger bubble to the smaller bubble till sizes are interchanged

C

Air flows from smaller bubble to bigger

D

There is no flow of air
