what is the most questionable phrase when used in advertising?\no \secret formula\\no \medically proven\\no \variation in efficacy\\no \fda - approved\

Answer

Answer:

"secret formula"

Brief Explanations:

The term "secret formula" in advertising is often vague and lacks transparency. It doesn't provide consumers with clear - cut information about what the product contains, unlike the other phrases which have more defined and verifiable meanings (e.g., "medically proven" implies scientific evidence, "FDA - approved" is a regulated status, and "variation in efficacy" is a more scientific statement about product performance).
