[Link to question paper][1]

The question says:

> The phase transition from gas to solid is called 
(A) condensation. (B) evaporation. 
(C) polymerization. (D) sublimation

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 chem olympiad make a mistake, or is there something obvious that I am missing?
