I think it's A, because "very" seems like a weak word, and "nice" also seems like a weak word judging by the sentence. Hope I helped! :D
Answer: A - very nice.
The phrase 'very nice' could be improved by replacing it with a more specific word such as beautiful, or interesting because it is being used after other expressions 'most elegant' and 'fine', and it is expected a more specific and clearer meaning. 'Very nice' s frequent in spoken English, but it shouldn't be used too much in writing.
