Sorcery, 2BB (4) An opponent chooses one - You draw three cards; or you destroy up to two target creatures that opponent controls and that player draws up to three cards. Those creatures can't be regenerated.1 "All knowledge has its price." -Gerda Äagesdotter, Archmage of the Unseen

It does not target the opponent, but you still choose an opponent. [WotC Rules Team 1998/02/01]
The opponent chooses which option they want (this is a mode choice). If they choose the "destroy" option, you choose the zero, one, or two targets after that. [Barclay 2002/03/26]
