问题补充：

—Here are the designs. do you prefer?

—I think looks the most original.

A. What; that

B. What; it

C. Which; it

D. Which; that

答案：

A. What; that

B. What; it

C. Which; it

(答案→)D. Which; that

解析：考察代词用法。Which是指特定范围之内的某一个，根据上文的the designs,可知是指几个设计中，你更喜欢哪一个？what是没有任何范围限制的。故排除AB。根据句意第二空应该是指那一个看起来最原始的。It指代上文出现的同一事物，而本题并没有考察这一点。
