请教GWD 18-11

In no other historical sighting did Halley’s comet cause such a worldwide sensation as did its return in 1910-1911.

A.did its return in 1910-1911
B.had its 1910-1911 return
C.in its return of 1910-1911
D.its return of 1910-1911 did
E.its return in 1910-1911

答案是A,不过我看不懂这句话的意思，its的指代对象我也搞不明白。

In no other historical     .in its return of 1910-1911,

平行对应, 都做状语.主语是Halley’s comet ,谓语CAUSE ......

As 或
                than 引导的比较从句，比较从句的主语和谓语相通时，
            可以全部省去，
            常常保留做状语的介词短语或状语从句

答案到底是A还是C啊。。。晕

请NN确认～
