Hi there!
Your answer is:
Dependent variable: Plant growth
Independent variable: Day length
Explanation:
The independent variable is Intentionally manipulated by the researchers. We know exactly what it will be each day, because we control it! Since the scientists are controlling the day length, that is your independent variable.
The dependent variable is NOT manipulated by the researchers. We are studying what the dependent variable does in reaction to the changing independent variable. Since we are recording & studying how the plant grows based on the day length, that is your dependent variable!
I hope this helps!

I guess it just works that way
It would be = A because it is winning something to a survey and a survey answer can be related going to a party
