Best Answer

(b) When the open end of an empty bottle in pushed inside water the water does not enter into it as it is filled with air. As the bottle is tilted slightly the air comes out and is seen in the form of bubbles. When the air comes out the bottle becomes completely empty and water rushes into it to occupy that empty space.
