Matter is simply defined as anything that has mass and occupies space.
So option B and C, for your option A, gases have mass and occupy space, so they are indeed matter. However for D, we have neutrinos, they are very small particles that are invisible but they do have an extremely small amount of mass(not sure about that) but there are disputes, since they r so hard to observe, their mass is not accurately calculated and occupy space. So neutrinos are matter even though they are invisible!
