Hint: When a soft drink cap is open what will be the weight of that soft drink. Now we are going to discuss this in detail, as it increases when the cap is open or it will decrease or first increase and then decrease the weight of cold drink when it is open. Let’s go through it.

Complete answer:
A soft drink has its energy level when it is closed, the energy in the soft drink rushes out when it is opened because it contains some gas in the cold drink and its direction is also in forward direction. When a cold soft drink is capped then first it increases its weight then decreases its weight.

When you pop a soft drink bottle like soda or soda containing drink, the pressure inside the bottle decreases, then when you open the cap of the bottle the pressure increases and it moves towards forward direction thus the pressure first increases and then decreases.

Hence, the correct option is C.

Note: We have discussed the pressure inside the bottle and the pressure when the cap of the bottle is opened. A soft drink is kept on a table and when it opens the cap of the bottle the weight first increases and then decreases.
