Phase transition from gas to solid
I guess the diagram of phase changes you have in mind looks like this:



Indeed this says deposition is the right name for a gas-to-solid phase transition and I believe that this is the only correct term. 

The only thing I can argue why it is obvious here that condensation is the right answer (at least the closest) is that this is the only answer that gives a transition from fluid to solid. B and D are the other way around, and C is not really a phase change (although it could result in one).
