181.View the Exhibit and examine the PL/SQL package and procedure. You made changes to the COMPUTE_TAX function inside the EMP_ADMIN package body. Which statement is true after you recompile the EMP_ADMIN package body? A.The USE_P procedure remains valid. B.The USE_P procedure becomes invalid. C.The SHOW_DETAIL procedure becomes invalid. D.The EMP_ADMIN package specification becomes invalid and needs to be recompiled. 答案：A 解析： A：正确，这里user_p过程中调用的emp_admin.compute_tax(8000),这里其实是直接应用的包的申明，因此改变包体内容 是不会影响到它的 B：错误 C：错误，show_detail都没有显示出具体内容 D：错误，包体的修改，对包的申明是没有影响的
