Unsupported. The author says nothing about whether the work of the New Women had any effect on social customs in the first place, so their work doesn’t tell us anything about which approach is more or less effective.

Unsupported. The author says nothing about whether the New Women advocated social change or regretted anything.

Misdirection. If this is supported, it’s supported by the work of the local colorists, not the New Women. The local colorists witnessed the decline of “women’s culture” and changed their literary techniques in response. Even then, to say that (C) “inevitably” happens is too strong too conclude based on a single example. Meanwhile, we're only interested in the New Women for this question. And nothing suggests that they were responding to, or trying to make sense of, social changes. They were just innovative.

Unsupported. It was Chopin, under the influence of the local colorists (not the New Women), who depicted extreme psychological states by using an uninflected manner. (Also, nothing suggests how accurately she was able to do so, or whether it was the most accurate approach.) Meanwhile, we're only interested in the New Women for this question. And, as far as we know, their only way of depicting psychological states was to use elements of fantasy and impressionistic methods. Nothing suggests they used an uninflected manner or depicted extreme psychological states.
