I really don’t know I put my wallet after I paid the bill．
A. where was it
B. it was where that
C. where was it that
D. where it was that

A. where was itB. it was where thatC. where was it that(答案→)D. where it was that解析：句意：我真的不知道，我在付款之后，究竟把钱包放哪了。通过分析句子结构，可知这个句子中包含一个宾语从句和一个强调句。强调句式的特殊疑问句是“特殊疑问词+ is/was+it that…?”，且宾语从句要用陈述语序，选D。
