Correct Answer is C. ALLOW WRITE ACCESS . Allows write access to the table during reorganization. This behavior is the default.https://www.ibm.com/docs/en/db2/11.5?topic=commands-reorg-table#sdx-synid_allow_write_access

The correct answer is A, the inplace option Rearranges the table while allowing user access. And the RESETDICTIONARY option if the COMPRESS attribute of the table is YES, a new row compression dictionary is constructed. https://www.ibm.com/support/knowledgecenter/es/SSEPGG_11.1.0/com.ibm.db2.luw.admin.cmd.doc/doc/r0001966.html
