Answer:
Engel v. Vitale.
Step-by-step explanation:
The Supreme Court case of Engel v. Vitale was a case of imposing school prayer in a school or academic establishment. The court ruled that this mandated school prayer was unconstitutional and that students/ American people do not have to adhere to join in the prayers if they don't want to.
The Establishment Clause of the First Amendment states that the government cannot make any law that will prohibit an individual from practicing a religious belief. It also stated that the government cannot impose a person to follow a particular religion nor impose any state or official religion.
The Engel v. Vitale case was a result of a school's 'demand' that the students recite the Pledge of Allegiance with the lines "Almighty God, we acknowledge our dependence upon Thee, and we beg Thy blessings upon us, our parents, our teachers, and our country. Amen." This was objected to by some parents of different religious beliefs that it is contradictory to their faiths. Led by a Jewish man, Steven I. Engel, the parents filed a complaint against William J. Vitale, Jr., the school board president.
The court ruled that it is indeed unconstitutional to impose mandatory school prayer in a public school.
Thus, the correct answer is option C.
