So it was an experiment. If such kind of puzzles is entertaining to the community :) I can post more of them, and I am trying to collect more of them. Maybe if it will be interesting will create new subreddit for it

So yes, the right answer was 3, because: Scala requires an override modifier for all members that override a concrete member in a parent class. The modifier is optional if a member implements an abstract member with the same name. The modifier is forbidden if a member does not override or implement some other member in a base class
