The Chicago Mercantile Exchange (CME), one of the world's largest futures and options exchanges, was originally known as the Chicago Butter and Egg Board when it was established in 1898.
It was primarily set up to facilitate trading in dairy products like butter and eggs. Over time, the exchange diversified its product offerings and was renamed to reflect its broader range of commodities and financial instruments.

(A) Chicago Board of Trade: A separate entity specializing in grain and commodity futures.
(C) Chicago Financial Exchange: Not the original name of CME.
(D) Chicago Stock Exchange: A separate stock exchange in Chicago.
Hence, option (B) is the correct answer.
