What does truth‑in‑advertising mean?

• A. All claims must be legal in fact
• B. All claims made in advertisements must be accurate and supported by evidence
• C. Advertisements can exaggerate claims for emphasis
• D. Advertisers do not need to provide proof for statements

Answer: (B)

The main idea is that all factual claims in an advertisement must be true and backed by evidence. This ensures that what a company says about a product can be checked against real data or testing results, so consumers aren’t misled. If a claim is tested or tested results are used, the advertiser should have credible proof to support it. Exaggeration or puffery—like saying something is “the best ever”—may be tolerated as opinion, but any statement that makes a factual claim about performance, quality, or effect needs substantiation. The other options miss this point: requiring only legality doesn’t guarantee truth, exaggeration for emphasis can be misleading, and saying no proof is needed contradicts the need for verifiable evidence.
