Information for detecting unauthorized input from a terminal would be BEST provided by the:

A.
console log printout.

B.
transaction journal.

C.
automated suspense file listing.

D.
user error report.

Explanation:
The transaction journal would record all transaction activity, which then could be compared to the authorized source documents to identify any unauthorized input. A console log printout is not the best, because it would not record activity from a specific terminal. An automated suspense file listing would only list transaction activity where an edit error occurred, while the user error report would only list input that resulted in an edit error.
