as a separate action this knowledge informed both his literary style and the content of his fiction; the intended meaning is that Ryunosuke Akutagawa‘s knowledge of European, Chinese, and Japanese literature was instrumental in his development as a writer
because this knowledge informed both his literary style and the content of his fiction. Further, Option B fails to maintain parallelism among "Europe", "China", and "that of Japan"; please remember, all elements in a list must be parallel. Additionally, Option B suffers from pronoun ambiguity, as it is unclear whether "it" refers to "knowledge" or "development". Besides, Option B uses the needlessly wordy phrase "as it informed", leading to awkwardness and redundancy.
C: Correct. This answer choice correctly refers to the singular noun "knowledge" with the singular verb "was". Further, Option C uses the phrase "informing both his literary style and..."; the use of the "comma + present participle ("verb+ing" - "informing" in this sentence) conveys the intended meaning - that Ryunosuke Akutagawa‘s knowledge of European, Chinese, and Japanese literature was instrumental in his development as a writer

Additionally, Option C correctly maintains parallelism among "Europe", "China", and "Japan". Option C also avoids the pronoun error seen in Options B and D, as it uses no pronouns. Moreover, Option C correctly uses the idiomatic construction "both A and B". Besides, Option C is free of any awkwardness or redundancy.
D: Trap. This answer choice suffers from pronoun ambiguity, as it is unclear whether "it" refers to "knowledge" or "development".
E: This answer choice incorrectly refers to the singular noun "knowledge" with the plural verb "were". Further, Option E incorrectly uses the unidiomatic construction "both A in addition to B"; remember, “both A and B" or "A as well as B" are the correct usages; A and B must be parallel and comparable.
