Ah, the age-old debate: reactant vs. independent variable. I'm going to have to side with option A on this one. It's basic science, folks.

Definitely, the reactant is the independent variable in the fitted line plot.

I agree, the reactant is the independent variable in this case.

I think option A is correct. The independent variable is the reactant.

Wait, did they just say 'reactant' instead of 'independent variable'? Clearly, the correct answer is A. These test writers need to go back to chemistry class.

This question is a real head-scratcher. I'm going to go with option E - it just makes sense that when the reactant increases, the expected yield would increase.
