Cursor variables (REF CURSOR types) in Oracle PL/SQL have 4 attributes: %ISOPEN, %FOUND, %NOTFOUND, and %ROWCOUNT. These attributes provide information about the cursor's state. The statement claims there are 4 attributes, which is correct for cursor variables (though note: implicit cursors have additional attributes like %BULK_ROWCOUNT and %BULK_EXCEPTIONS, but for cursor variables specifically, there are 4 main attributes).
