It took me 3min 30sec i was happy in the end that i could nail down the right answer the fact of the matter being we have to nail down the right tense the noun should refer to the right person keeping all that bottlenecks in mind let us figure out the answer
A) was launched with Rachel Carson’s Silent Spring, and he outlined his beliefs in his essay, “Nature,” arguing that man does not fully accept nature’s beauty and all that it has to offer.
arguing and accept are not in the same tense hence i eleminated
(B) launched itself with Rachel Carson’s Silent Spring, and outlined his beliefs in his essay, “Nature,” which argued that man does not fully accept nature’s beauty and all that it offers.
it was not the environment that had launched the argument isn't clear
(C) launched with Rachel Carson’s Silent Spring; he outlined his beliefs in his essay, “Nature,” which argued that man does not fully accept nature’s beauty and all that it has to offer.
The tenses are in sync there is a relative clarity in the tenses let us hang on to this one
(D) launched Rachel Carson’s Silent Spring; Emerson outlined his beliefs in his essay, “Nature,” arguing that man does not fully accept nature’s beauty and all that it has to offer.
Afain same problem as A
(E) was launched with Rachel Carson’s Silent Spring; in it he outlined his beliefs in this essay, “Nature,” arguing that man does not fully accept nature’s beauty and all that it offers.
here too there is a tense problem for example arguing and offers are not in sync
Hence IMO C
