Why would you be cautious of scientific information you hear from advertisers?

The correct answer will be- advertisers do not provide enough data to support the scientific information (pseudoscience).

Explanation:

The man-made products like food, cosmetics and other useful products by the industries are not a reliable source of the scientific information related to the product.

The consumer should not depend on advertisers for scientific information of the product as the aim of the company is to gain profit and the provided information if any is not supported by the evidence as they do not provide enough sources.  This lack of data is considered the practice of pseudoscience which is based on the co-incidences and belief system.

Thus, advertisers do not provide enough data to support scientific information (pseudoscience) is the correct answer.
