In a certain electronic product promotion meeting, a certain electronic product was particularly popular with consumers. When summing up the experience, the person in charge of the promotion meeting said that it seems that only electronic products that have invested a lot of advertising costs to promote can have good market acceptance. Which of the following, if true, would most question the statement of the person in charge? ['The design of an electronic product adds more technological elements, although it is not advertised, it is still welcomed by the market.', 'The advertising group most concerned about electronic products is young people, and the consumers who participated in this promotion happened to have more young people.', 'A certain electronic product has invested a lot of advertising costs to promote it, but because its price is too high, it is not welcomed by the market.', 'Some electronic products have invested heavily in advertising, but they do not actually have some of the functions advertised.']
