Full Explanation
C is correct because in PROC TEXTMINE, the LDA statement with NTOPICS= specifies the number of latent topics the algorithm should discover from the document corpus. A is wrong because TOPICS= is not a valid PROC TEXTMINE statement option. B is wrong because K= in LDASVD is used for the SVD step, not LDA topic count. D is wrong because TOPIC= is not a dataset option that controls the number of LDA topics.
