Solution

The correct option is A
Direction of air flow does not depend on the volume. It depends only on the difference in pressure between two points. Air always flows from higher to lower pressure.
The pressure inside the B block is higher than that of the A block. Therefore, the air will flow from B to A block after opening the valve.
