The correct answer will be-observing the circumference of balloon.
Explanation:
The research performed to prove any hypothesis is of two types- qualitative analysis and quantitative analysis based on which the results could be qualitative as well as quantitative.
The qualitative data provides the information about the phenomenon which can be just observed and not measured while the quantitative data gives information about the quantity by providing a value.
In the given case, the students want to measure the amount of CO₂ by collecting the gas in the balloon. The qualitative aspect of this experiment can be measured by observing the circumference of the balloon as more amount of CO₂ produced more amount of gas trapped in balloon. This changes the circumference of the balloon.
Hence, observing the circumference of the balloon is the correct answer
