Yes. When two things are directly prortional, that means that as one increases, the other increases at the same rate. So, say you have a 2kg object at an acceleration of 2m/s^2. The force would be 4N. If you have a 3kg object at an acceleration of 2m/s^2, the force would be 6N. If two things are inversely proportional, that means that as one thing increases the other decreases at the same rate. A good example of this is in a chemical reaction. If you increase the surface area of the reactants, the reaction time decreases. They are inversely proportional.
I believe the answer is D
