Which scenario is allowed under the free-exercise clause?

a parent leads a prayer in a public park.
a teacher gives out crosses at school.
a doctor charges religious patients less money.
a worker places a menorah in the lobby at city hall

The correct answer is a parent leads a prayer in a public park.

The free exercise clause is part of the first amendment of the Bill of Rights. This clause allows citizens to practice any religion they want. Along with this, it prevents the government and any organization/institution affiliated with the government from endorsing a specific religion. This explanation shows why option b and option d are incorrect, as these are not protected by the free exercise clause.

With this first amendment right of freedom of religion, individuals cannot discriminate against others if they don't practice religion. This is why option c is wrong as well.

C. a parent leads a prayer in a public park.
