Starting with D
0 divided by any number is still 0. So D is correct
C is 2/2(x+0.5)=1/(x+0.5). Therefore we subtract to equal quantities of opposite signs. C must be also 0
B essentially is x-x Therefore B must be = to 0 as well
A -1 divided by any number different from zero will be never zero itself
B, C, and D are the correct options
