Where am I going wrong with this:

If the length of chord is 8.
The radius must be joining both end of the Chord and forming a triangle where the two opposite radius will give angles 45, 45, and thus angle at the centre becomes 90. This makes this a 1:1:Root 2 triangle and hence Radius 4 root 2.

Can you please help?

The red part is not correct. Why do you assume that?

Given: In the rectangular coordinate system, points (4, 0) and (– 4, 0) both lie on circle C.
Asked: What is the maximum possible value of the radius of C ?

The is no finite maximum value of radius C since these 2 point (4,0) & (-4,0) can form an arc of a infinitely large circle C.

IMO E

The opposite angles will be equal but how do you figure that they will be 45 - 45 each? They could be 10 degrees each or 80 degrees each etc.
