Step-by-step explanation:
The most suitable method for reaching a large consumer market segment with a broad class of buyers would be D.magazine advertising. This form of advertising has the potential to reach a wide and diverse audience. Magazine ads are especially useful if the consumer market segment shares common interests or demographics that align with the readership of various magazines. Additionally, magazine advertising can be beneficial as it allows for full-color, creative presentations of the product or service, often leaving a lasting impression on the reader.
Despite the move towards digital media, there are still significant segments of the consumer market that utilize traditional channels like magazines.
