D
do you think ...后面跟的一个宾语从句,提问时要将宾语从句的特殊疑问词提到句首,因此可以这么看这个句子：
where () he () the computer?
即他在哪里买的电脑?原本应该是did / buy,但宾语从句规定从句的语序要用正常语序,即主+谓,因此不需要向平时一样将助动词提前到主语,保持正常陈述句语序,he bought 就可以
因此D是正确的

D./;bought
插入语do you think后面要用陈述语序，故A，B,C错。

选C.do you think 是插入语。“你认为他在哪里买的这台电脑？”强调过去的动作，所以用过去时。

D./; bought
如果去掉插入语 do you think, 就是很单纯一条问句： Where did he buy the computer?
加了 do you think ，后面成为宾语从句，did he buy 就不能用了，必须改为 he bought.
