You're wise to us if you chose A. The roots of "wizard" stretch back to the Old English word "wis" meaning "wise." English speakers used "wis" to form "wysard," which eventually became "wizard." "Wizard" is related to "wisdom" and "wise," both of which also trace to "wis." "Wiz" and "whiz" are shortened forms of "wizard." So when we tell you that you're a word wiz, it also means you're word wise!
