Full Explanation
B is correct because PROC DMDB creates a descriptive metadata file about dataset variables (types, class levels, statistics) required as input by SAS data mining procedures including PROC NEURAL, PROC CLUSTER, and others. A is wrong; scoring uses PROC ASTORE or PROC SCORE. C is wrong; SVD is performed within PROC TEXTMINE. D describes a data preparation step, not PROC DMDB's function.
