Answer:
Scientific/technical evidence
Explanation:
When an advertiser cites technical information, such as the results of laboratory studies, in an advertisement, a scientific/technical evidence style of execution is being used. This information is much important for the customers for certain products and services. For example, Toothpaste making companies use to highlight that their toothpaste has been approved by certain dental associations and some highly useful and recommended chemicals also present in their toothpaste which are very useful for the protection of teeth and gums. Likewise, when shampoo making brands highlight use of certain chemicals in their ads etc.
