Answer 2

B. Point B is opposite of Point C

Explanation:

Let B (x1, y1) and C (x2, y2) be two points.

if sum of B and C is 0:

([x1 + x2]/2, [y1 +y2]/2 ) = (0, 0)

then

[x1 + x2]/2=0 then x1+x2 = 0 then x1 = -x2

similarly, [y1+y2]/2 = 0 then y1+y2 = 0 then y1=-y2

Therefore,

B= (-x2, -y2) while C = (x2, y2)
