The correct answer is Plessy Vs. Ferguson. In the landmark case Plessy vs. Ferguson, it was ruled that segregation of facilities was constitutional as long as those facilities were equal in quality. This is were the term "Separate but Equal" comes from. However, during the case Brown vs. The Board of Education it was ruled that racial segregation violated the fourteenth amendment of the Constitution. It was this ruling that rendered the ruling in Plessy vs. Ferguson invalid because the ruling was unconstitutional.

<h3>What is
halo effect?</h3>
The halo effect refers to the tendency for positive impressions of a person, company, brand, or product in one area to influence one's opinion or feelings in other areas.
The halo effect refers to a consumer's preference for a line of products because of previous positive experiences with this manufacturer's products. The halo effect is associated with brand strength, brand loyalty, and brand equity.
The halo effect occurs when you judge a person's qualities by other unrelated, usually physical, qualities, as the name suggests. A sharply dressed coworker, for example, may be perceived as more competent than a coworker wearing a t-shirt. Edward L., an American psychologist, coined the term in 1920.
