I found a similar DS problem on here, but the B statement was different.
So here goes:
thank you
In the rectangular coordinate system, are the points (r,s)..

IMO it should be E
A, B do not tell anything about the distance from the origin,
combined together also do not tell anything about distance
r+s=1, r, s=1/2 will have distance of (1/2)^0.5
u+v=1, u=3/4, v=1/2 will have distance of (13/16)^0.5 different
or if u,v=1/2 then same distance. so cannot tell
