The sealed bottle.
Reason: CO2 solubility in the liquid is proportional to the CO2 partial pressure in the headspace (Henry’s law). A sealed bottle maintains the high internal pressure so the liquid holds the most dissolved CO2. Once opened the pressure drops and CO2 comes out of solution, so the longer it’s open the less dissolved gas remains.
