Which of the following is best supported by the passage?
- AThe diet causes most users to lose a great deal of weight.
- BNinety per cent of users regained the weight afterwards.
- CThe advertisement is illegal under consumer law.
- DThe advertised statistic is consistent with results that are trivial or short-lived.
