Show answer & explanation
Correct answer: A
Concept
A predictive data-mining workflow begins with data, extracts meaningful information from it, and applies a defined process to discover patterns or construct a model.
These are conceptual building elements: the data is the raw material, information is its interpreted form, and the process is the set of analytical operations.
Application
In the given list, (i) names the data set, (ii) names the information set, and (iv) names the process set. Together they cover the source material, the meaning derived from it, and the operations applied to it.
Contrast
(ii), (iv) and (v) combines information and process with the produced output rather than the source data.
(i), (v) and (vi) combines source data with output and a test set, which is used later for evaluation.
(ii), (iii) and (v) combines information, model input, and output but leaves out the analytical process.
Cross-check
Following the abstraction from raw facts to interpreted meaning and then to analytical operations gives data set → information set → process set.
Therefore, the required combination is (i), (ii) and (iv).
