The correct option is
B Magazines
The correct answer is Option A.
There are two conditions mentioned in the question. We are to identify the advertising medium that- 1. caters to a specific audience and 2. suffers from the drawback of less flexibility.
Both television and radio (option B and C) suffer from the drawback of less flexibility cause advertisements cannot be altered easily, but they cater to a wide range of audience. Therefore Option B and C are not the correct options as they do not satisfy the criteria given in the question.
Newspaper as an advertising medium does cater to a specific audience to some extent as only the literate can read a newspaper, but otherwise it has the advantage of flexibility as changes can be made in newspaper advertisements. Hence option D is the incorrect option.
Magazines are printed on various subjects- fashion, business, etc. Thus specific advertisements in a magazine cater to only that particular audience. Also, magazines are not printed on a daily basis, therefore, it is difficult to make changes in the advertisement. Thus it suffers from the drawback of less flexibility. Therefore both the criteria satisfied, Option A is the correct answer.
