Answer:
Argument from authority
Step-by-step explanation:
An argument from authority or appeal to authority (argumentum ad verecundiam) is a type of argument based on the opinion of a celebrity or well-known individual. It's an example of a logical fallacy - a flaw in reasoning. Just because someone is well-known in a certain field doesn't mean that they are right.
For example, if someone believes that vaccines cause harm, they can use the opinion of a famous doctor who has the same opinion as they do to support their argument. However, that doesn't make their argument valid. We need to approach every topic with caution and make sure to research it objectively.
