it is you obtain.you must tell your parents. A．Whatever,that B．No matter what,/

________it is ________you obtain，you must tell your parents.

A．Whatever；that 　 B．No matter what；/

C．What；that 　 D．Whatever；/

A　

考查强调句型。如果将其还原就比较简单了：Whatever you obtain，you must tell your parents.该强调句强调的是whatever；第二个空中的that是强调句中的that，因此B、D选项是错误的；C选项中的what只能引导名词性从句，不可引导其他从句。
