Answer: D
A snapshot tool is most useful when an audit trail is
required. ITF can be used to incorporate test transactions
into a normal production run of a system. CIS is useful when
transactions meeting certain criteria need to be examined.
Audit hooks are useful when only select transactions or
processes need to be examined.
