问题补充：

A. what he wants to do
B. what does he want to do
C. what he want to do
D. what will he want to do
答案：
(答案→)A. what he wants to do
B. what does he want to do
C. what he want to do
D. what will he want to do
解析：句意：当他长大时，他打算做他想做的事情。英语宾语从句中一般用陈述语序，结合语境可知本句宾语从句中描述的是客观性的动作，故用一般现在时态。主语he是单数第三人称，故谓语动词用单数，选A。
