Explanation:

                 Miranda right is also known as Miranda warnings sometimes. It is the right given to a suspect to remain silent and the right to have an      attorney.

                 When an investigator is asking questions to the suspect person for a crime, the Supreme court says that after the suspect waives off the Miranda rights, the investigator can continue to interrogate him  until the suspect makes clean and unambiguous request for a lawyer.

                Thus in the context, Sam waives off the Miranda rights provided to him and is willing to give answers to the detective's question. But when he is not sure whether he wants a attorney or not, the detective under the Supreme Court rulings, can ignore his request and continue questioning Sam until he makes a clear request to have an attorney for himself.

Hence the answer is--

D. may ignore Sam's statement and continue asking questions until Sam makes an unambiguous request for an attorney.
