scientists are trying to develope a special material,__ they will make use of in spacecraft a it b
scientists are trying to develope a special material,__ they will make use of in spacecraft
a it b one c that d what

B
A显然不对句意不通
B指代material 做make use of的宾语做宾语的先行词引导词that可省略
C没有先行词而且that是不可以引导非限制性定语从句的（一般就是两个分句指用逗号隔开的后面半句）它只能引导限制性定从
D的what=the sth that 这里就相当于the meterial that 与前半句重复要改用which就可以成立
其实我觉得 D选项放在这边很难解释但是which是成立的 what相对于which 我认为就一定是不成立的而且我也说了与前面半句重复句式太啰嗦了你不确定的话可以再问别人
