Questions: Which one of the following is perhaps the main advantage associated with the use of advertising? A It takes little time to develop an advertising campaign. B It is extremely cost efficient. C It can quickly convey a large amount of technical information. D It always has large returns.

The answer is B It is extremely cost efficient.

Developing an advertising campaign typically requires significant time and effort. This includes market research, creative development, media planning, and execution. Therefore, this option is not a main advantage of advertising.

Advertising can be cost-efficient, especially when reaching a large audience. The cost per impression or per potential customer can be relatively low compared to other forms of marketing, such as direct sales efforts. This efficiency is one of the main advantages of advertising, particularly in mass media.

While advertising can convey information, it is generally not the best medium for detailed technical information. Advertisements are typically designed to capture attention quickly and may not provide the depth of information that other methods, like brochures or detailed presentations, can offer.

While advertising can lead to significant returns, it is not guaranteed. The effectiveness of an advertising campaign depends on various factors, including the message, medium, target audience, and market conditions. Therefore, it is not accurate to say that advertising always has large returns.
