In a science classroom, a teacher sets up an experiment where a test tube is filled with water and a green plant called elodea. The test tube is then placed in a sunny spot. After a while, students observe that the plant starts to produce bubbles. The teacher asks the class to deduce the most likely identity of the gas in the bubbles.

• Carbon dioxide

• Oxygen

• Nitrogen

• Hydrogen
