Answer:
A. School prayer was banned in public schools across the United
States.
Step-by-step explanation:
In the case of Engel v. Vitale (1962), the court defined as contradicting the Constitution the development by a certain agency of the State of New York of the text of the prayer for students of a free high school. Although the prayer was clearly neutral from the point of view of faiths, the Supreme Court firmly stated that officially supported religious events were tantamount to introducing a state religion and therefore contrary to the Constitution.
