A television commercial argued as follows: both the product advertised and its competitor contain the same active ingredients, but the product advertised contains them in higher concentrations; tests show that the higher concentrations are completely safe; since a product that provides faster relief is always preferable, one should use the product advertised. The television commercial's argument is most vulnerable to criticism on the grounds that it
A: takes for granted that the product with the higher concentration of active ingredients provides faster relief than its competitor
B: attempts to manipulate the emotions of potential customers of the advertised product rather than presenting logically sound reasons for preferring the product advertised
C: attempts to establish its conclusion on the basis of evidence that is in principle impossible to disprove
D: dismisses its competitor's claims because of their source rather than their content
Choose A, B, C or D as your solution.
