Question

which policy do the plaintiffs disagree with in brown v. board of education?○ separate but equal○ equal protection under the law○ the dred scott decision○ the emancipation proclamation

Explanation:

The Brown v. Board of Education case challenged the legal doctrine that allowed racially segregated public facilities, arguing that separate educational facilities were inherently unequal and violated the Equal Protection Clause. The "separate but equal" policy, established by Plessy v. Ferguson, was the core policy the plaintiffs opposed. The other options are unrelated: equal protection was the principle they argued for, the Dred Scott decision concerned enslaved people's citizenship, and the Emancipation Proclamation abolished slavery in Confederate states.

Answer:

separate but equal
