D Correct answer
Explanation

Find the event NOT on May 3rd. The US never had a 20¢ coin in circulation in 1878 - the 20-cent piece was minted 1875-1878 but was discontinued, not 'stopped minting on May 3, 1878.' The other events are correctly dated to May 3rd: DC incorporation (1802), Kasparov-Deep Blue (May 3, 1997), and Oklahoma tornado (May 3, 1999).
