The company that manufactures ski boots might prefer to advertise in specialized publications because of the greater audience selectivity of the specialized publications.
Specialized publications are print or digital media outlets that focus on specific niche topics, industries or interests which provides in-depth and specialized content catering to a particular audience.
Magazines like Ski and Skiing cater specifically to individuals interested in skiing and related activities which means that the audience is highly targeted and composed of potential customers who are more likely to be interested in ski boots.
So, this selectivity allows for a more efficient use of advertising resources, as the message reaches a higher percentage of potential buyers. Therefore, the Option 2 is correct.
