Which type of advertising appeal is being used when advertisers emphasize negative outcomes of not using a product or changing a​ behavior?

Advertising with a positive appeal is always made in spite of its negative impacts.

Explanation:

No.1. Every advertiser tries their best to make the best product available to the consumer.

No.2. Every advertiser is aware of the negative effects or outcomes of the side effect. They try their best to allay fears of the consumer and make the product presentable.

No.3. Negative effects should be reduced or eliminated to a normal level. The advertiser should try to focus on the positive side, rather than bringing out its negativeness.
