The above equation represents a circle with radius 5 and center (0,0)

1) The Y co-ordinates of both A and B points are identical

Case 1: Let A = (5,0) & B = (-5,0)..........AB is the diameter of the circle =10

Case 2: Let A = (3,4) & B = (-3,4)..........AB is less than length of the diameter.

Insufficient

2) X and Y co-ordinates of both points A and B are integers

Case 1: Let A = (5,0) & B = (-5,0)..........AB is the diameter of the circle =10

Case 2: Let A = (3,4) & B = (-3,4)..........AB is less than length of the diameter.

Insufficient

Combine 1 & 2 using same examples above, no certain length of AB

Insufficient

Answer: E
