Answer:
The correct answer is Humorous.
Step-by-step explanation:
Opera buffa was a genre originated in Naples, Italy, in the first half of the 18th century. Its stories revolve around a comedic situation or character, in an everyday setting, and with simple vocal writting. It is shorter than the vast majority of operas, commonly containing only two acts.
It is believed to be a lighter form of opera that distances itself from Opera seria (serious opera), making it easier for the uneducated folk to understand and enjoy.
