Guys just need a small help on this

In the attached question Aren’t both C and D the plausible answers on this, depending upon what co-ordinate u take?

Ok here is the question
THe co-ordiante of three of the vertex of the rectangle are (2,3) (2,5) and (4,3) respectively. What is the co-ordinate of the centre of the rectangle.

(2,3)
(3,2)
(3,3)
(3,4)
(4,3)

if u take A as (2,3) B (2,5) and C (4,3), therefore centre of the rectangle will be the midpoint of the diagonal A(2,3) and C(4,3) which is (3,3)
if u take A as (2,5) B (2,3) and C (4,3), therefore centre of the rectangle will be the midpoint of the diagonal A(2,5) and C(4,3) which is (3,4)

but, if (2,5) and (4,3) are opposite vertices, the mid-point has to be (3,4)
Can you explain your choice of C?
