B,D Correct answer
Explanation

COMPRESSION HIGH is available for all internal LOB types (BLOB, CLOB, NCLOB), not just CLOBs, making option B correct. The DECRYPT option can remove encryption from LOB columns regardless of whether they contain data or are empty, making option D correct. Option A is incorrect because compression isn't limited to CLOBs, and option C is incorrect because the DECRYPT option works on non-empty columns too.
