问一个关于句子完整性的问题

justabeginning

84. Often visible as smog, ozone is formed in the
atmosphere from hydrocarbons and nitrogen oxides,
two major pollutants emitted by automobiles, react
with sunlight.
(A) ozone is formed in the atmosphere from
(B) ozone is formed in the atmosphere when
(C) ozone is formed in the atmosphere, and when
(D) ozone, formed in the atmosphere when
(E) ozone, formed in the atmosphere from
这题的正确答案是B
我的问题是如果把D选项变成forms in the stomosphere when,并把它和ozone之间的逗号去掉是否就变成正确答案了呢？

感觉意思还是变了一些。forms when感觉更倾向于表示“反应以后的结果”，而原文的倾向有所不同。

此外，often (is) visible..., ozone does....  前后是否有不一致的说法？不太清楚了，就是感觉怪。

mmmmmignon

不可以的
即使去掉逗号，formed都做ozone的后置定语，该句子谓语的.
如果要强行把form作为verb的话就表达不出被动的意思了 被动是be done
