Answer:
1st amendment
Step-by-step explanation:
If an employer prevents someone from taking a job because of the candidate's religion, as happened with Maya, shown in the question above, that employer is preventing religious freedom, which is the right that allows any American citizen to join to any religion without suffering reprisals for it.
When someone does not obey religious freedom, it causes a disobedience of the first constitutional amendment that protects that right.
