D) TV ads
In a business-to-business (B2B) context, TV ads are the least likely to be used as an advertising and promotion method. B2B marketing typically involves reaching a more targeted and specialized audience, often other businesses or professionals. Methods like trade magazines, direct sales, and trade shows are more commonly employed to reach this specific audience and convey detailed information about products or services. TV ads are generally better suited for reaching a broad consumer audience in a business-to-consumer (B2C) context.
