D, opera
Extra information:
Songs were not cultivated in Italy, neither were symphonies. Concerts do mainly originate in Italy, but they do not have anything to do with the romantic era. The Opera, however is considered one of the most romantic musical forms and was cultivated in Italy. Therefore the correct answer should be Opera.
If people were too poor to own instruments, most people could use buckets as drums , glass jugs to make beats , their hands and feet to also make beats , and use their voices to sing. I tried my best , hope this helped!
