Full Explanation
B is correct because SVDINIT in PROC TEXTMINE configures the Singular Value Decomposition step, which reduces the high-dimensional term-by-document matrix to a lower-dimensional latent semantic space. Parameters include the number of SVD dimensions (K=). A describes stop word handling, which is part of the PARSE step. C describes sentiment analysis configuration. D describes LDA initialization, which uses a different statement.
