Correct option is D)

While drinking a soft drink with the help of straw the pressure in the straw is less and the pressure in the bottle is higher. When the air from inside the straw is sucked out, it creates a region of lower pressure inside the straw. As the pressure inside the bottle is more, the liquid is pushed upwards in the straw.
