I go by the books:
my answer is A because generally in a parallel reaosning question always try and parallel 3 elements:
1. the validity of the argument
2. the conclusion
3. the premise
in this order
Also if you look at option A the author arrives at the conclusion based on a past action
Hence we have to choose an answer that indicates the effect now based on an action of the past( which is advertising in a newspaper)
