Answer:
The real answer is "it was Felix Mendelssohn who" (which is not available)
Explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
Unfortunately none of these answers are correct. Answer two "would" be correct if the sentence continued and didn't end with a period. The rest of the answers are all grammatically incorrect. The only grammatically correct answer would be "it was Felix Mendelssohn who" which is a mix of the first two available answers but not a single available answer.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
