Solution

The correct option is A
True

Siphon works on the basis of the difference in pressure. A portion of air inside the bottle moves out when the bottle is pressed and released. The pressure inside the bottle thus decreases. This pressure difference makes water to flow from the high-pressure to the low-pressure region. Therefore the atmospheric pressure will push the water up and thus flows through the bottle as shown below.

Therefore, the given statement is false.
