B. Internal auditors perform a systems-focused analysis to review relevant controls. (Incorrect)

This relates more to evaluating control effectiveness rather than exploratory data mining.

Does not directly contribute to identifying new audit areas.

Testing IT general controls is a structured evaluation, not an exploratory data mining technique.

Exploratory data mining is used to identify risks before formal testing occurs.
