Solution

C is correct. Data mining bias comes from overuse or misuse of the data and can result in finding models or patterns where none exist.

A is incorrect. Sample selection bias often results when data availability leads to certain data being excluded from the analysis.

B is incorrect. Look-ahead bias exists if the model uses data not available to the analyst at the time the analyst act on the model.
