The answer to this is A. It is important that the correct figures are figured out because even a little amount will have a possibility to change the results. There are times when the results that are given by experimentation are not accurate simply because of people’s mistake in computing the right amount of materials that will be used.

Now, it is clear that the proper answer is 1000 mL and 500 mL. The other given choices are too high for the given amount. The figures will change considerably if the amount of gravity will be changed. This plays a huge role in the possible outcome of the experiment.
