1) The Zero Property of Division states that 0/x = 0. (not to be confused with the Division into Zero property, where x/0 = undefined...since it's not an option, I'd probably go with b. Identity Property of Division because it's similar and maybe the person who made the questions included the one inside the other)
2) e. The -1 Property of Multiplication states that -1x = -x.
3) e. The Identity Property of Multiplication states that 1x = x.
4) b. The Identity Property of Division states that x/1 = x.
