(B) added to which is English, Spanish, and Italian words
(C) to which English, Spanish, and Italian words have been added
(D) with English, Spanish, and Italian words having been added to it（C）
(E) and, in addition, English, Spanish, and Italian words are added
The underlined section must modify the noun phrase seventeenth-century French by noting additions made to French subsequently from foreign vocabularies. C, the best choice, does this clearly, directly, and correctly in the form of a relative clause. Because the subject of this clause is plural (words), the verb must also be plural (have been added). A and B incorrectly use singular forms has been added and is added. B also awkwardly inverts and divides the verb phrase (added... is). D offers an awkward adverbial construction, which cannot be used to modify nouns. E offers an incoherent and incomplete new clause with the wrong verb tense and no logical complement for are added that is, we are not told to what the words are added.
