Phase transition from gas to solid

Question 13 from the [ACS chemistry olympiad](http://www.acs.org/content/dam/acsorg/education/students/highschool/olympiad/pastexams/2011-local-olympiad-exam.pdf) exam:



> 
> The phase transition from gas to solid is called 
>  \begin{align}
> &\text{(A) condensation.} & \text{(B) evaporation.} \\ 
> &\text{(C) polymerization.} & \text{(D) sublimation.}
> \end{align}
>

I am pretty sure the answer is deposition, which is not listed, but yet the answer is (**A**) **condensation** [scroll to the end of the question paper to see the answer key].


Did the chemistry olympiad make a mistake, or is there something obvious that I am missing?




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).
