The Chicago Mercantile Exchange (CME), a major global futures and options exchange, was established in 1898 as the Chicago Butter and Egg Board.
Initially, its purpose was to trade dairy products such as butter and eggs. The exchange later expanded its offerings to include a wider array of commodities and financial instruments, leading to its renaming.
Explanation of Other Options:
(A) Chicago Board of Trade: A distinct exchange focused on grain and commodity futures.
(C) Chicago Financial Exchange: This was not the original name of the CME.
(D) Chicago Stock Exchange: A separate stock exchange located in Chicago.
Therefore, option (B) is the correct choice.
