The police were convinced that Melinda robbed the BANK. They arrested her, read her Miranda rights, and held her for questioning for 60 hours. Although she repeatedly asked for an attorney, the police would not allow her to contact one. She was kept awake during the entire 60 hours, not given water when she asked for it, and denied bathroom privileges. Finally, exhausted and near hysteria, she confessed to the BANK robbery. She provided details that only the bank robber could know, and it was clear she was guilty. Melinda's confession is

a. Inadmissible because the confession was elicited in direct violation of Melinda's 5th Amendment rights.
b. Inadmissible because Melinda had not been given her Miranda warnings.
c. ADMISSIBLE because Melinda was, in fact, guilty of the crime.
d. Admissible because Melinda ultimately gave information which only the ebank robber could know.
