Data mining is a complex process that requires time and iteration to arrive at accurate results. It is time-consuming because it requires the analyst to go back and forth through the steps of the process multiple times until an accurate result is found. Therefore, option C, time-consuming and iterative, is the best choice. Option A is not the best choice because data mining is not a simple process. Option B is not valid because the data mining process does not necessarily require a lot of investment. Finally, option D is incorrect because the data mining process is not hypothetical.
