Solution

The correct option is D
Drinking straw

Drinking water with the help of straw works on the existence of atmospheric pressure.

While drinking water with a straw from a glass, the pressure inside the straw decreases when air is sucked from it. This decrease in pressure inside causes water to rise in the straw from the glass.
