Yes, C is right. The following will show you why that is right.
PV = nRT
Say P, R, T are some constant numbera. Just for the fun of it let's say RT/P = 10 so now that equation is
V = 10n. So if n = 1 (that's 1 mol) then V is 10
If n = 2 mols then V is 20. What happened to V when we doubled mols (that's n). V went from 10 to 20. It doubled, This should make it plain why that happens.
