Answer: B. is an attempt to convince people to adopt a particular viewpoint.
Step-by-step explanation:
The advertisement claiming that if one uses a particular brand of toothpaste one will become popular is pseudoscience it has no scientific basis. It is just to mold the perception and thinking about the toothpaste. It is not supporting the fact that toothpaste can help in improving the teeth quality, making teeth clean, and germ free instead indicating towards social acceptance by others with the use of toothpaste. How can one get popular among other people is not mentioned also it is a propaganda to increase the sale of the product as everyone wants social acceptance so the advertisement is supporting that with the use of toothpaste one will get socially accepted by others.
