I do believe that the hardest part of an art critique is all based on opinion. Some have trouble with finding flaws, some with finding the good things. It all depends on you. Are you giving the critique or getting it?
The correct answer is indeed D. Italian.
Giacomo Puccini was a famous Italian composer of the 19th century. He composed La Boheme, which is an Italian opera about four artists who are very poor but happy. One of them falls in love with Mimi, who suffers from tuberculosis and eventually dies.
