Final answer:
The opera 'Porgy and Bess' was premiered by the Chicago Opera Company in 1935, not by the New York Metropolitan Opera, the Berlin State Opera, or the Royal Opera House in London.
Step-by-step explanation:
The opera group that premiered "Porgy and Bess" was B) The Chicago Opera Company. "Porgy and Bess" is an opera by George Gershwin, and while one might think of the New York Metropolitan Opera as a potential premiering company due to its prominence, "Porgy and Bess" actually had its debut with the Chicago company in 1935.
The practice of doing a "test run" in other cities, as mentioned, is common in the industry to assess the success potential, such as with shows like "Kinky Boots", which opened in Chicago, or "Moulin Rouge" which premiered in Boston before going to Broadway.
