Answer:
Second option
Step-by-step explanation:
Your answer is the second option or the dependent variable. Always remember that the variable you're testing is the independent variable and the variable you are measuring is the dependent variable. Some common examples of dependent variables would be something like the amount of water used to water a plant. The height of the plant after you watered it for a certain amount of weeks. If you're measuring something in an experiment that is the dependent variable.
